Abstract

Specifically designed for use with a centimetre wavelength, phase contrast, microwave detection system this antenna operates at a centre frequency of 5 GHz. The design utilises off the shelf RF switches for ease of implementation. The ability to be switched between two orthogonally separated polarisation conditions allows separate E plane measurements to be conducted. A wide bandwidth capability permits antenna placement optimisation and a swept measurement capability. Dual probe feeds ensure ease of construction whilst the low Q nature of the device enables a wide operating frequency.
