Abstract

We propose a compact, high-efficiency antenna configuration, which is 18cm in diameter and has average gain of 24.1 dBi for automotive applications of satellite TV systems operating at Ku band. To achieve high aperture efficiency, hybrid microstrip, and waveguide feed network with low-loss microstrip-to-waveguide transition is designed and validated. The array antenna is wideband and covers entire downlink Ku-band frequencies (10.8-12.75GHz) for simultaneous reception from multiple transponders. Vertical polarization panel is built and tested for reception quality. Carrier-to-noise ratio of 6.2dB was observed the target transponder (42 degrees E) at 11.9GHz using intermediate frequency loop-out of the receiver. The antenna can be used on small vehicles or automobiles for satellite TV reception.
