Spiral Antennas

Our range of Spiral Antennas provide low cost, excellent wideband performance in a compact package, with either left or right hand Circular Polarisation. Spiral antennas are used in many applications because of their cost and size. They are used in EW applications such as Radar Warning Receiver (RWR) systems and as Threat Warning Antennas in threat warning receivers.
0.5 - 18 GHz Spiral antenna

0.5 - 18 GHz Spiral Antennas

The QSPCP0.5-18S is a compact 152mm diameter, ultra-wide band circularly polarised antenna spiral suitable for UWB communications and Direction Finding, (DF) applications. This is designed to allow for specific performance modifications to meet customer requests. LHCP and RHCP versions are available.
