CubeSat UHF Antenna System

The minimum order quantity for this subsystem is 20 pieces.

NanoAvionics UHF Antenna System consists of RF Splitter and 4 monopole antenna. RF Splitter is a key element in turnstile antenna systems that performs 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.
