Abstract :
The paper presents realization, mechanical solution and measurements results of a receive system used in the Demonstrator of an S-band Active Antenna. The receive system employs 16 antenna rows of planar array to form fin-beam receive antenna pattern in elevation plane and pencil-beam in azimuth. Five elevation positions of a pencil receive beam is electronically set by means of digital phase shifters and attenuators applied in receive beam forming network. The receive system realizes sum and difference beam signals for both azimuth and elevation planes at beam former outputs. Brief description of the whole receive path with main blocks is presented. The results of antenna pattern measurements on a tower setup are shown.
