Abstract
A microstrip patch antenna wherein the half-power beamwidths of two orthogonal polarizations can be widened or narrowed in desired frequency bands around its center frequency. The result is a wideband or multiband antenna with desired beamwidth characteristics. In particular, the antenna can be arranged to be singly-polarized, dual-polarized or circularly-polarized. Using at least two parasitic patches on each of the two opposing sides of a primary radiating patch, both E-plane (electric field) and H-plane (magnetic field) parasitic couplings can be simultaneously achieved. By introducing uneven current distribution along the patch principal axis, some sub-bands of the antenna pattern can be beam steered.
