An integrated 3×8 element phased array receiving antenna combined with a 4×8 element transmit antenna for 5.8 GHz DSRC Dedicated Short Range Communication has been built. The number of analog phaseshifters and antenna elements has been optimized to meet the specific requirements of the application and of the DSRC-standard. A sophisticated concept for the(More)
Low-cost planar microstrip single elements and arrays suited for multichannel multipoint distribution systems (MMDS) and microwave video distribution systems (MVDS) at 40GHz have been designed. The problem of realising dedicated 90° sector antennas with high roll-off characteristics which are impossible to achieve with other antennas in a cost efficient way(More)
An 8/spl times/8 element array antenna for 1.71-1.785 GHz frequency range suited for an adaptive antenna system has been built. The elements are broadband microstrip patches, which are optimized for large angular coverage. The antenna can be digitally switched between 16 different polarizations to enhance polarization-diversity-gain. Calibration ports allow(More)
