Meet Experts, Make Friends was the motto for the 16th European Microwave Week that found a new home at the Nürnberg Convention Centre, NCC Ost from Sunday 6th to Friday 11th October. A higher number of unique delegates, along with exhibitors and visitors were able to discover that the beautiful city combines the culture, entertainment and history of a large metropolis, while affording the charm and warmth of a much smaller city. Whether in the conference sessions, workshops and short courses, on the exhibition floor or socialising at the Welcome Reception there was the opportunity to foster relationships, both professional and personal.

Although it is the first time that EuMW has been held in Nuremburg, exactly 30 years ago, in the days when Germany was divided into East and West, the city was the venue for the 13th European Microwave Conference. In the three decades since, The Wall has come down, along with barriers to trade and been replaced by initiatives aimed at nurturing and encouraging technological innovation.

EuMW2013Since its inception European Microwave Week has played its part in marrying the needs and aspirations of academia and industry and in 2013 EuMW again played matchmaker by fostering cooperation and collaboration. In Nuremburg there was the opportunity to meet experts throughout the three conferences: The European Microwave Conference (EuMC), European Microwave Integrated Circuits Conference (EuMIC) and the European Radar Conference (EuRAD), on the show floor at the European Microwave Exhibition and beyond.

For instance, the opening and closing plenary sessions of each of the three conferences featured keynote speeches by world leaders in their fields and a welcome address by the President of the IEEE. In a separate session he was joined on a Presidents’ Panel by the presidents of EuMA, IEEE MTT-S, and VDE/ITG. And, acknowledging, the increasing significance and influence of the Asian market there was also a special all-invited session on the Asia-Pacific Microwave Conference.

Those that can probably benefit greatly from meeting experts and making friends are the students and young engineers who were the focus of a number of focused initiatives – namely: The European Microwave Doctoral School that featured world leading microwave scientists and engineers as distinguished lecturers, and the European Microwave Student School that was devoted to microwave measurement techniques. In addition, eligible students competed in the Student Challenge, which is a poster competition, alongside the Student Design Competition, which is a design and measurement competition.

The Women in Microwave Engineering focused on the challenges induced by the current trends towards the Internet of Things and cyber physical systems, while the one-and-a-half day Defence and Security Forum considered the differences and commonalities of defence and automotive radar.

Automotive technology was a common theme as an academic subject, workshop topic and practical illustration on the exhibition show floor as cars and trucks demonstrated that automotive technology is emerging from the lab and onto the road. Specifically, a 250 m strip of road adjacent to the exhibition hall where Mercedes-Benz dramatically demonstrated the application of automotive radar sensors.

Larger in gross space and the number of exhibiting companies than in 2012 the exhibition hall was a hub of activity and a focus for the poster sessions, coffee breaks and the Cyber Café. The European Microwave Week Microwave Application Seminars (MicroApps) held in the MicroApps Auditorium in the exhibition hall continued to develop, with some sessions being standing room only and Panel Sessions often being platforms for lively debate and interaction.

As well as meeting experts and making friends the exhibition is the place to come face to face with the latest technology, establish and reengage contacts and do business. It is also a platform for innovation that leading manufacturers often choose to launch new products and float future concepts. In NCC Ost, Hall 7A, there were over 280 exhibiting companies. Below is a selection of the new and innovative products on show.

A new company that we have not seen before was Aaronia of Germany. They had some very interesting products such as magnetic tracking antennas for low frequency (1 Hz to 1 MHz), high directivity applications.  The interesting part is that they are made with cascadable gain elements that can be added by attaching additional tubes. They also make handheld spectrum analyzers, desktop and military grade spectrum analyzers and many other types of antennas.  

Exhibit1Agilent Technologies Inc. introduced a pulse measurement option for its FieldFox handheld analyzers that is designed to further simplify radar field testing. With the new pulse-measurement option, the analyzers allow users to carry a single instrument into the field to verify and measure radar pulse characteristics, S-parameters, spectrum analysis and transmitter power. The FieldFox pulse measurement option efficiently characterizes radar signal quality by leveraging Agilent U202x peak-power sensors (available in 18 GHz and 40 GHz models). With a single push of a button, users can perform pulse characterization in the field and obtain all key performance indicators.

Among its large portfolio of products on display Agilent showcased the M9391A, a 1 MHz to 3 GHz or 6 GHz PXIe vector signal analyzer, with up to 160-MHz bandwidth designed to test the latest wireless standards.

Exhibit2Computer Simulation Technology (CST) will be previewed the latest version of its flagship electromagnetic simulation tool, CST STUDIO SUITE® 2014, which builds on the company's extensive range of electromagnetic simulation tools with new features to help Engineers to capture system effects as well as to optimize individual components in a streamlined workflow. It includes several new features to make it easier to import, manipulate and export models from CAD and EDA software.

System Assembly and Modelling (SAM) is CST's most powerful tool for integrated design, allowing multiple full-wave 3D and circuit simulations to be combined, together with analysis and optimization, into a straightforward series of tasks to be carried out automatically. CST STUDIO SUITE 2014 builds on the capabilities of SAM, with simplified multiphysics workflows, more PCB functionality, and support for nearfield sources in the frequency-domain and integral equation solvers.

Alongside these system-level enhancements are a range of performance and usability improvements to existing solvers to optimize calculations and increase support for high-performance computing techniques such as GPU and MPI computing. The transient and frequency-domain solvers in CST MICROWAVE STUDIO® (CST MWS) also support new meshing techniques for both tetrahedral and hexahedral meshes, which can greatly reduce mesh-cell count on complex geometries such as imported CAD files. This speed up in simulation can make it easier to simulate electrically very large structures without drastic simplification.

Copper Mountain was impressing EuMW visitors with their compact Network Analyzers and reflectometer product lines, including their R140 vector reflectometer, planar 808/1 “full-size” VNAs and 5048 compact VNA. The highly portable R140 (attached to a demo antenna) can operate in any environment without the use of a test cable and is fully programmable using COM/DCOM automation. With a frequency range up to 14 GHz, it’s an alternative to other field instruments that users wouldn’t think of leaving behind in a remote site. The new 808/1 VNA offers a high performance 4 port network analyzer with a frequency range up to 8.0 GHz. The compactness and innovative engineering behind Copper Mountain products should have engineers in the market for a cost and size friendly VNA to take a serious look at their offerings.

EM Software & Systems previewed the release of FEKO Suite 6.3. Support for curvilinear meshes in connection with Higher Order Basis Functions (HOBF) has been added for MoM and MLFMM. The curvilinear meshing allows larger elements without sacrificing model accuracy, which can result in significant reductions in run-time and memory requirements for some structures. Also, Antenna designers will no longer have to be concerned about the angle increments that are used to sample far field radiation patterns or RCS plots as FEKO can automatically compute a continuous representation of the data. The plotting of continuous far field data can then be sampled with any resolution in POSTFEKO.

Characteristic modes are now tracked by correlating modes between individual frequencies of a sweep. The mode tracking is based on ordering the modes correctly at each frequency relative to their rankings at the reference frequency (typically the first frequency point). This algorithm makes working with Characteristic Mode Analysis (CMA) even more intuitive. CMA has also been extended to support dielectric and magnetic materials with MoM with the surface equivalence principle and apertures with the planar Green's function. Numerous extensions have been made to the cable modelling interface including selection and snapping to cables in the 3D view, definition of cable paths at a constant distance from model faces, improved searching with the Find cable tool and rectangle selection in the schematic view.

Gore featured RF and microwave cable test assemblies that ensure precise, repeatable measurements for the life of your test equipment. The long-lasting, reliable performance of these durable assemblies delivers low loss, reduces total cost of test, and improves system reliability. These cables have excellent phase and amplitude stability with flexure, wide operating temperature range, and crush and torque resistance. They did a survey which showed that 55% of test cables do not last even one year so reliable cables are critical to keeping costs down. They were also showing off their box right angle connectors that operate up to 40 GHz. They use a swept contact for a low loss transition even though the form factor looks like a right angle.

Hittite was highlighting many products such as their 2 W power amplifier covering 15 to 20 GHz with 25% PAE, GaAs MMIC SP4T reflective switches operating from 23 to 30 GHz and optical modulator driver solutions - 28 Gbps EML and 32 Gbps MZ drivers.

The surface mount 7x7mm plastic package offers a cost-effective, easy to implement solution.

MAGUS Ltd and CST are developing new tools for linear antenna arrays including feed networks, to launch with the newest version of Magus' flagship product Antenna Magus. The tool allows a feed network to be synthesized either as part of a patch array design (the N-by-1 microstrip patch array with corporate feed), or in isolation to be used with arbitrary antenna elements. The feed network uses practical microstrip lines, and the network topology is automatically adjusted according to the number of elements. The feed network models can be exported into the 3D EM simulation tool CST MICROWAVE STUDIO® and their behaviour simulated and optimized as necessary using the full-wave solvers available in CST MWS. With this new feature, the two companies hope to allow feed effects to be considered earlier in the design flow, and streamline the antenna simulation workflow.

Microwave Innovation Group (MiG) presented a number of useful additions and extensions to its fast WASP-NET hybrid EM CAD tool. An advanced fast integral equation (IE) solver completes WASP-NET’s seven solver hybrid mode-matching (MM)/finite-element (FE)/method-of-moment (MoM)/finite difference (FD)/finite element-boundary-integral (FE-BI)/physical theory of diffraction (PTD)/physical optics (PO) EM CAD engine to perform high CAD efficiency for complex and large antenna structures. Examples are shaped dual reflector antennas with feed-networks, large antenna arrays, e.g. slot-arrays with complete layered feed-networks, where all mutual couplings are rigorously taken into account, Vivaldi and patch arrays, reflectors with struts and layered, lossy radomes, reflect-arrays, and radar cross-section (RCS) investigations at large structures.

An extended 3D editor for user-defined structures enables users to combine full 3D flexibility with WASP-NET’s high calculation speed. Geometry dimensions are parameterized for fast optimizations; lossy materials as well as dielectric and ferrite materials with frequency dependent tensor permittivity/permeability can be included; available 3D CAD data of components or component parts can be imported via standard formats and parameterized to be combined full-wave with desired further elements or user defined 3D structures, for fast, direct EM overall optimization.

New synthesis wizards streamline the design flow for user-friendly designs of filters and slot-arrays. A new integrated M-matrix designer automatically carries out basic filter design synthesis steps starting from given specifications, and proposes appropriate filter topologies. The fast hybrid multi-solver 3D EM CAD engine of WASP-NET enables designers to apply immediately and efficiently rigorous fast EM optimization. In this way, filters and arrays can be efficiently optimized with full accuracy directly on the EM level.

Phase Matrix was featuring their QuickSyn® microwave synthesizers that deliver instrument-grade performance, increased functionality, and efficient power consumption at a reduced size and low cost. The synthesizers employ a patented phase-refining technology that provides a unique combination of fast-switching speed and low phase-noise characteristics. They cover the frequency ranges of 0.5 to 10 GHz and 0.5 to 20 GHz (extendable down to 0.1 GHz and 0.2 GHz). QuickSyn® synthesizers utilize a fundamental VCO to achieve the desired output frequency. In contrast to frequency multiplication schemes, this approach eliminates possible spectrum contamination from subharmonic products. The use of the advanced direct digital synthesis approach, enables a very fine frequency resolution of 0.001 Hz. The VCO noise is suppressed by utilizing an ultra low noise reference oscillator in conjunction with a low-noise locking mechanism. Microphonic effects are also greatly reduced due to the use of a low-mass VCO and very wide PLL filter bandwidth.
