A new design of a patch antenna with a three‐dimensional inverted V‐shaped patch is proposed and experimentally studied. The three‐dimensional inverted V‐shaped patch is formed by bending a conventional planar rectangular patch at its centerline into an inverted V‐shape, and it is then supported by nonconducting posts above a ground plane. The proposed antenna can be excited by using a microstrip feed line through a coupling slot cut in the ground plane of the microstrip line. From the experimental studies, it is found that the proposed antenna can have an enhanced 3 dB beamwidth compared to conventional planar patch antennas when the excitation direction of the inverted V‐shaped patch is perpendicular to the patch's bent centerline. © 2000 John Wiley & Sons, Inc.
