Patent ID: 7852279

Claim:
A miniature conformal polarization-independent antenna, comprising: a cavity having a mouth and located in a conductive substrate; quadrature antenna elements at the mount of said cavity; a phasing module coupled to the feed points of said elements for measuring the right hand circular polarized component and the left hand circular polarized component of a signal at said antenna; and, a unit within said module for calculating the angle of arrival of a wave incident on said antenna by measuring the right hand circularly polarized components and the left hand circularly polarized components of the wave and for generating an angular correction factor compensating for the polarization of the incoming wave, the angular correction factor being derived from the right hand circularly polarized components and the left hand circularly polarized components of the wave incident on said antenna and the electronic rotation of said antenna, said angular correction factor being a function of the complex amplitude difference in the outputs of pairs of said antenna elements.
