ABSTRACT:
A miniature conformal antenna is provided with a polarization-independent output by using quadrature elements at the mouth of a cavity and by processing the RHCP and LHCP outputs of the elements to arrive at a polarization-dependent solution; and then correcting the angle of arrival result by electronically rotating the antenna, measuring the amplitude difference between element pairs at various angles, generating an amplitude difference curve and deriving an angular correction factor therefrom.
