Wideband patch antenna with L-shaped probe

摘要

An antenna design comprises a patch that may be rectangular, circular, triangular or any other geometric shape and which is disposed by a dielectric a distance above a ground plane. The patch is driven by an L-shaped probe disposed between the patch and the ground plane. The probe has a first portion normal to both the patch and the ground plane, and a second portion parallel to the patch and the ground plane. The lengths of the two portions are selected so that the inductive reactance of the first portion is cancelled by the capacitive reactance of the second portion. In alternative embodiments a plurality of such patch antennas may be connected together via a single transmission network to form an antenna array.
