Abstract:
An integrated directional patch antenna uses multiple patch radiating elements to control the direction of a beam of radio frequency energy (RF) over a large scan volume. The antenna includes a ground plane element and a first dielectric planar member placed on a major surface of the ground plane element. A plurality of first patch radiator elements is arranged on a surface of the first dielectric member remote from the ground plane element. A second dielectric planar member is placed on first patch radiator elements, and a plurality of second patch radiator elements arranged on a surface of the second dielectric member remote from the first patch radiator elements. First regions are formed in the dielectric planar member that have a first dielectric constant and are separated from each other by second regions that have a dielectric constant different from the first dielectric constant to effectively prevent surface wave energy from propagating in the first dielectric planar member, thereby increasing the scan volume of the antenna.
