Dual-patch antenna and array

摘要

A dual-patch antenna includes a ground plane (46), a first patch plate (40a) parallel to and separated from the ground plane by a separation distance, and a second patch plate (40b) separated from the ground plane by the separation distance. The first and second patch plates are coplanar and separated by a radiating slot (56). An excitation probe isolatedly passes through the ground plane and connects to the first patch plate. A first wall (48) connects an edge of the first patch plate to the ground plane. The first wall is located approximately 1/4 wavelength of a mid-band operating frequency from the radiating slot. A second wall (54) connects an edge of the second patch plate to the ground plane. The second wall is located approximately 1/4 wavelength of the mid-band operating frequency from the radiating slot. The dual-patch antennas may be organized in an array.
