Abstract :
Microwave receivers that incorporate lens-fed planar antennas with semiconductor components integrated on common substrate, in an area small enough for packing into monolithic two-dimensional arrays, are described. Such receivers have been built to operate at 10 and 35 GHz. A radar demonstrator has also been built, using a hybrid array and it has shown direction-finding accuracy comparable to monopulse, in a staring array with no moving parts.<>
