摘要：
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.
