Abstract

A dual offset Gregorian system leaky-wave antenna realized in PCB technology has been presented. An antenna prototype has been manufactured and tested. The measured radiation patterns as a function of the frequency have been presented. A pins-made feed, that uses EBG concepts, PCB extension of the one presented in [4] has been used to efficiently feed the dual reflector system. However it has not been discussed here for the sake of brevity. Good performance of the antenna has been observed. The planar dual reflector system could be used in future planar imaging system applications, to achieve antennas with independent beams in the azimuth and elevation planes, resorting to frequency reuse and multiple focal plane feeds. The scanning of the pointing angle with the frequency is observed. In particular since the final user of these antenna is a radar system whose beam is scanned as a function of the frequency, the frequency squint that was observed in Fig. 3 should not be considered a disadvantage.
