Abstract
An electronically steerable antenna for L-band satellite communication, the antenna comprising: a patch antenna including: four antenna elements spaced apart in a patch plane to form a two-by-two grid with a spacing between each antenna element of less than a half wavelength, a ground plane, and one or more controllers configured to apply difference beam steering to the four antenna elements; and a crossed metallic fence electrically connected to the ground plane and extending through the patch plane between the four antenna elements to separate the four antenna elements into respective quadrants in the two-by-two grid.

An electronically steerable antenna for L-band satellite communication, the antenna comprising:
- a patch antenna including:
- four antenna elements spaced apart in a patch plane to form a two-by-two grid with a spacing between each antenna element of less than a half wavelength,
- a ground plane, and
- one or more controllers configured to apply difference beam steering to the four antenna elements;
- and
- a crossed metallic fence electrically connected to the ground plane and extending through the patch plane between the four antenna elements to separate the four antenna elements into respective quadrants in the two-by-two grid.
An electronically steerable antenna for L-band satellite communication, the antenna comprising:
- a patch antenna including:
- a top patch array including four top patch elements spaced apart in a top patch plane to form a top patch two-by-two grid,
- a bottom patch array including four bottom patch elements spaced apart in a bottom patch plane to form a bottom patch two-by-two grid corresponding to the top patch two-by-two grid, and
- a feed coupler array including four feed elements arranged in a ground plane to form a ground plane two-by-two grid corresponding to the bottom patch two-by-two grid,
- wherein the top patch array, the bottom patch array, and the feed coupler array together form a two-by-two antenna array;
- and
- a crossed metallic fence extending from the feed coupler array, through the bottom patch array between the four bottom patch elements, and through the top patch array between the top patch elements to extend above the top patch elements.
