Abstract :
A hybrid theoretical/experimental approach to the design of radial line slot array (RLSA) antennas for receiving direct broadcast satellite (DBS) TV programs in Australia is presented. Using this approach, 0.4-m and 0.6-m diameter linearly polarized Ku-band prototype antennas were constructed and experimentally investigated. The 0.6-m prototype incorporates reflection cancelling slots, which allow it to overcome the inherent poor return loss performance in linearly polarized RLSA antennas. Measurements show high-radiation efficiency for this form of radial slot antenna and its suitability for the DBS TV application
