The NanoAvionics UHF antenna system consists of an RF splitter and four monopole antennas. RF splitters are an important element of a turnstile antenna system that performs impedance matching and splits a single RF signal into a phase network to form a single circularly polarized antenna. This provides an almost omnidirectional radiation pattern with no blind spots, which can lead to signal fading due to satellite tumbling. Apertures can be provided inside the splitter board for hardware integration purposes.
