A Low Profile CPW and Microstrip-fed Half Circle Planar UWB Antenna

The authors describe a low profile CPW and microstrip-fed half-circle planar monopole antenna with a dual rectangular slit, which has similar radiation pattern properties for ultra-wideband applications. In this case, the inserted dual slit on the monopole also leads to enhancing the wide band impedance. The inserted dual slit on the monopole and feeding structures (CPW-fed and microstrip-fed with a dual open-stub) also leads to reducing antenna size and enhancing wideband impedance matching characteristics. The antenna has a low profile of 24 mm x 30 mm x 1 mm. The measured bandwidth is from 2.92 to 11.7 GHz for a return loss less than -10 dB. The proposed antenna also has a peak gain of 4.5 dBi.

Wireless Signals as You’ve Never Seen Them

What You Should Know About MIMO Operation and Measurement

A selection from Agilent’s “Ten Things You Should Know About MIMO” are presented in this paper, with the intention of giving the user an overview of the operation of MIMO technology and test methodology. Each item uses an example to highlight the impact on the radio system or associated test. A poster that summarizes all ten points is available from Agilent on request (order information can be found at the end of this paper).

A Low Cost Wafer Scale Package Technology for mm-wave Applications

In this paper, wafer scale packaging information is shown including factors that make it low cost. RF I/O design and tested performance for the wafer scale package are shown. After the discussion of the wafer scale package design, the design and performance of a broadband driver amplifier is described.

LTE ARQ and Re-segmentation

Re-segmentation effectively enables more flexibility in the LTE eNB scheduling of resources. Instead of rigidly maintaining constant resource constraints for re-sending data, the eNB can quickly and efficiently change resource grants to suit the radio conditions, thereby balancing the resource needs of all users of that eNB.

Theoretical Analysis on Attenuation of the 5 GHz Miniaturized GaAs MMIC Bandpass Filter

A theoretical analysis method on attenuation of the compact GaAs MMIC bandpass filter using the structure of a diagonally short-ended coupled-line with capacitive loading, which is a potential solution to achieve extremely miniaturized size, is given in this paper. Based on this model, the factors related to the insertion loss performance are investigated. The experimental verification shows good agreement between theory and experiment. The proposed scheme can be used in the design and optimization of this kind of new miniaturized bandpass filter.
