Abstract

This paper describes a microstrip array antenna designed to operate at 35 GHz, and used as a position detector of moving targets. To obtain a wide detection range, the array was arranged to have a relatively narrower beamwidth in the elevation plane compared to the beamwidth in the azimuthal plane. This was achieved by aligning the electric‐field plane of each element to the array axis. Employing a 3 dB tapered feed network, the array has a sidelobe level of less than −20 dB, while retaining a wide azimuthal beamwidth. © 2001 John Wiley & Sons, Inc.
