Abstract
A laminar microstrip patch antenna includes a ground plane dement having opposing first and second faces, a first dielectric planar member adjacent a first face of the ground plane element, a patch radiator on a face of the first dielectric member remote from said ground element, a second dielectric planar member adjacent a second face of the ground plane element, and a transmission line circuit for feeding the antenna. The transmission line circuit is located on a face of the second dielectric member remote from said ground plane element, and the ground plane has an aperture to couple the transmission line circuit to the patch radiator. The aperture is formed as a cross made up of two intersecting linear slots. The transmission line circuit is formed by two linear conductors intersecting each other at a single electrically insulated point, the intersection point being aligned with a center of the intersection of the aperture cross with the linear conductors lying between the slots of the aperture.
