A broadband, circularly polarized antenna system suitable for use on WP-3 aircraft and operating in the VHF-UHF frequency region has been designed and fabricated. This airborne radiometer system will operate over a 3 to 1 frequency range without tuning. The installation contains a high- and low- frequency hemispherical coverage antenna and a high- and low- frequency fan-beam array. The entire installation is designed to fit into the the standard APS-20 radome of the WP-3. Use has been made of a novel antenna element to achieve good pattern performance in such a confined space. Emphasis has been placed on low loss and reliable operation.
