Dual-patch antenna and array
First Claim
1. A dual-patch antenna array, comprising:
- a plurality of dual-patch antennas, each dual-patch antenna comprising;
a ground plane;
a first patch plate parallel to and separated from the ground plane by a separation distance;
a second patch plate separated from the ground plane by the separation distance, coplanar with the first patch plate, and separated from the first patch plate by a radiating slot;
an excitation probe isolatedly passing through the ground plane and connecting to the first patch plate;
a first wall connecting an edge of the first patch plate to the ground plane, the first wall located approximately ¼
wavelength of a mid-band operating frequency from the radiating slot; and
a second wall connecting an edge of the second patch plate to the ground plane, the second wall located approximately ¼
wavelength of the mid-band operating frequency from the radiating slot,wherein the radiating slots are colinear.

Abstract
A dual-patch antenna includes a ground plane, a first patch plate parallel to and separated from the ground plane by a separation distance, and a second patch plate separated from the ground plane by the separation distance. The first and second patch plates are coplanar and separated by a radiating slot. An excitation probe isolatedly passes through the ground plane and connects to the first patch plate. A first wall connects an edge of the first patch plate to the ground plane. The first wall is located approximately ¼ wavelength of a mid-band operating frequency from the radiating slot. A second wall connects an edge of the second patch plate to the ground plane. The second wall is located approximately ¼ wavelength of the mid-band operating frequency from the radiating slot. The dual-patch antennas may be organized in an array.
