This paper presents millimeter wave phased array antenna for short range communication applications at 35 GHz. The antenna array is formed by 1 × 16 microstrip antipodal tapered slot antennas each connected to RF MEMS phase shifters for beam steering. The simulation and measurement results of the single antenna element are presented and the phase shifter structure to be used in the array is described...
The demand on advanced personnel screening systems led to the development of several active and passive imagers. Among them, active multistatic imaging ensures high image quality and allows fully electronic screening. An active -band imager is presented in this paper, which measures in real-time and delivers images of 30-dB dynamic range. Imaging of humans is achieved by optimizing the acquisition...
Temperature change cause thermal expansion of the antenna materials and will have an important impact on antenna performances. In some applications it is sufficient to calculate the antenna deformation due to temperature by mechanical analysis and determine the RF impact by EM analysis tools. However, if the environmental conditions of the final antenna are stringent and considered critical as in...

This paper presents analysis results of the wideband MIMO channel based on indoor measurements. An accurate characterization of the K-factor is very important in design issues, especially for MIMO and broadband networks. We have performed measurement campaigns for the indoor wideband channel using the Band Exploration and Channel Sounding (BECS) system developed by ETRI at 3.7 GHz with 100 MHz RF...
This paper presents the design and development of a module of a phased-array antenna for multimedia contents reception in mobile avionics applications. The antenna, which operates in Ku band (12.5 GHz to 12.75 GHz), is based on a modular design. The developed antenna & RF front-end module is implemented in multilayer technology and it has been tested from an electrical, mechanical and thermal...
