CubeSat UHF Antenna

CubeSat UHF Antenna System

NanoAvionics UHF Antenna System consists of RF Splitter and 4 monopole antennae. RF Splitter is a key element in turnstile antenna systems that does impedance matching and splits one RF signal into a phasing network in order to form a single circular polarized antenna. This results in an almost omnidirectional radiation pattern with no blind spots, which can cause signal fading due to satellite tumbling. An aperture can be provided inside the splitter board for hardware integration purposes.
