Abstract
A low loss dual circularly polarized feed antenna for a high gain deployable K-band reflectarray antenna on a CubeSat platform is designed. The feed consists of an elliptical horn antenna and its feed network, which will be optimized alongside with the reflectarray to match the desired performance goals of the antenna system. The antenna system reaches a peak gain of 38.5 dBi in the 19.7-20.2 GHz band. The gain variation is less than 0.2 dB and the feed reflection coefficient is less than -23.4 dB throughout the bandwidth.
