Abstract

A beamwidth broadening technique for a microstrip patch antenna is presented here. The antenna consists of a patch radiator with two phase‐reversed auxiliary radiators. This technique allows the beamwidth of a microstrip antenna with a large aspect ratio to be broadened at the expense of a slight increase in its lateral size. By using the auxiliary radiators, up to 16% increase in the H‐plane beamwidth is achieved. This antenna is also analyzed using a modified aperture model. Other existing beamwidth broadening techniques are compared and their applications listed. © 2008 Wiley Periodicals, Inc.
