Abstract
A dual-polarized patch antenna, an dual-polarized patch antenna array, and a method for forming the same are provided. The dual-polarized patch antenna comprises a radome, a horizontal feed and a vertical feed, a first cross-shaped patch, and a ground plane including a cross aperture. The dual-polarized patch antenna may include a cross patch and a cross aperture to increase the isolation in a cross-polarization between a horizontal polarized signal and a vertical polarized signal in a first principle plane and to decrease a mismatch in co-polarizations between the horizontal polarized signal and the vertical polarized signal in a second principle plane.
Claims20
A dual-polarized patch antenna (100), comprising:
- a radome;
- a horizontal feed and a vertical feed;
- a first cross-shaped patch;
- and
- a ground plane including a cross aperture.
A dual-polarized patch antenna array (100), comprising an array of dual-polarized patch antenna elements, each respective dual polarized patch antenna including:
- a radome;
- a horizontal feed and a vertical feed;
- a cross-shaped patch;
- and
- a ground plane including a cross aperture.
The dual-polarized patch antenna array of claim 16, further comprising:
- a border formed around the dual-polarized patch antenna array, the border having a border width,
- wherein the border width is formed to match a phase of a dual-polarized patch antenna element to a phase of an outside edge of the border.
A method of forming a dual-polarized patch antenna array including a radome, a horizontal feed, a vertical feed, a cross-shaped patch, and a ground plane including a cross aperture, the method comprising steps of:
- forming the ground plane including a cross aperture;
- forming the cross-shaped patch;
- and
- assembling the radome, the horizontal feed, the vertical feed, the cross-shaped patch, and the ground plane.
