FEKO Suite 6.2

September 12, 2012

Suite6.2FEKO Suite 6.2 introduces several completely new features to FEKO.  Characteristic mode analysis (CMA) is the numerical calculation of a weighted set of orthogonal current-modes that are supported on conducting bodies (similar to waveguide modes). The eigencurrents are independent of any specific source or excitation and thus only depend on the shape and size of the conducting body.

2014 FEKO Student Competition

The popular FEKO Student Competition is once again open to all under-graduates and post-graduates who work on a supervised project in electromagnetic engineering and make use of FEKO. This annual competition is an opportunity for students to showcase their work.


A Novel RF Coupler for SMART Utility Meter Remote Antenna Applications

In this paper the authors investigate and present a patent pending novel micro-strip coupler structure that exhibits very low RF insertion loss (high coupling) while insuring high electrical isolation (>10kV) between the wireless Network Interface Card (NIC) RF connection and the external antenna.


Planar Structures

Microstrip filters, planar antennas and other RF structures are solved efficiently using the planar Green's function. Only the stripline or antenna needs to be discretised with this method. Ground planes are treated implicitly by the formulation and do not add to the number of unknowns.


Windscreen Antennas

Antennas are increasingly incorporated into the windscreens of automobiles. FEKO has a special formulation to design the antenna and calculate the effect of the vehicle on the radiation pattern of the antenna.


Radiation Hazard Analysis

The combination of the integral equation (MoM) and the differential equation (FEM) solvers allows the efficient solution of real world radiation hazard problems e.g. calculating the effect of an antenna's radiation on humans sitting inside a vehicle. SAR is calculated according to international standards.


Cable Harness Analysis

The combined MoM and the Multi-conductor Transmission Line (MTL) theory enables the analysis of coupling into and radiation from cable harnesses in their real-world environments.



Several extensions and special solvers are used in FEKO for efficient EMC analysis, e.g. adaptive frequency interpolation, cable harness analysis, SAR calculation, low frequency stabilisation, time domain analysis. Applications include shielding and coupling investigations, reverberation chamber design and EMC test environment modelling.


Waveguide and RF components

Offering both a MoM and a FEM solver FEKO is well-suited for the full-wave analysis of waveguide structures e.g. Magic-T coupler, slotted waveguide antenna, cavity- and waveguide filters. Port modes are specified or calculated and near-fields and S-parameters are extracted with ease.


Antenna Design and Placement with FEKO and Antenna Magus

App Note: Antenna Magus
A case study, showing the design of an array antenna for the proximity fuse of an air defence missile, is performed to illustrate the combined use of Antenna Magus and FEKO.
