CubeSat and SmallSat UHF Antenna System

The minimum order quantity for this subsystem is 4 pieces.

NanoAvionics has three types of UHF Antenna Systems. The CubeSat version consists of an RF Splitter and 4 monopole antennas integrated into the same sub-assembly. The microsatellite version consists of 4 monopole antennas and a supporting splitter, allowing greater flexibility in footprint and positions. The third group is a standalone monopole antenna assembly that deploys at 90 degrees and supports various applications.
An RF Splitter is a key element in turnstile antenna systems that performs impedance matching and splits a single RF signal into a phasing network to form a single circularly polarized antenna. This results in an almost omnidirectional radiation pattern with no blind spots and prevents signal fading due to satellite tumbling. An aperture can be provided inside the splitter board for hardware integration purposes.
