Abstract
An interleaved planar array antenna system providing opposite circular polarizations comprises an array of parallel rows of parallel spaced transmit dipole radiating elements and an array of parallel rows of parallel spaced receive dipole radiating elements. Both sets of dipole elements are on the same surface, with the receive dipole elements being oriented orthogonal to the transmit dipole elements and the rows of transmit and receive elements being interleaved. On another surface parallel to and spaced from the first surface, there is at least one transmit feed line which is proximity coupled to the transmit dipole elements and at least one receive feed line which is proximity coupled to the receive dipole elements. Polarizing means are spaced from and overly the transmit and receive dipole elements for transforming orthogonally oriented linearly polarized transmit and receive beams into oppositely circularly polarized transmit and receive beams.
