ABSTRACT:
An interleaved planar array antenna system providing angularly adjustable linearly polarized beams comprises an array of parallel rows of transmit dipole element pairs and an array of parallel rows of receive dipole element pairs, the two arrays being interleaved. Each of the dipole element pairs includes a first dipole element and a second dipole element adjacent and orthogonal to the first dipole element. All of the first dipole elements are parallel to each other and all of the second dipole elements are parallel to each other. All of the dipole elements are on the same surface and on another surface parallel to and spaced from the first surface there is an array of transmit feed line pairs and an array of receive feed line pairs, with the arrays being interleaved with each other. The transmit feed line pairs are proximity coupled to the transmit dipole element pairs and the receive feed line pairs are proximity coupled to the receive dipole element pairs. By controlling the relative amplitudes and phases of signals applied to the two feed lines within each feed line pair, the resultant angle of linear polarization of a composite signal from the respective dipole element pairs is adjustable.
