CubeSat and SmallSat UHF Antenna System

The minimum order quantity for this subsystem is 4 pieces.

NanoAvionics has three types of UHF Antenna Systems. Cubesat version consists of RF Splitter and 4 monopole antennas integrated into a same sub-assembly. Microsatellite version consists of 4 monopole antennas and supporting splitter, to allow more flexibility on footprint and positions. Third group is a standalone monopole antenna assembly, witch deploys 90degrees and allows various applications.
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.
