Abstract

This paper presents a small aperture shaped ring focus reflector antenna that covers the frequency band from 7.9 GHz to 9.1 GHz, featuring a wide bandwidth, low VSWR and low-cross-polarization levels. The proposed antenna is composed of a feed horn, a polarizer, a main- and sub- reflector. To validate the concept, an antenna prototype is manufactured and then tested. Both simulated and measured results of VSWR and radiation patterns are presented. The antenna is demonstrated to be able to achieve good performance and can be used in satellite high speed data downlinks.
