Abstract

In this paper, a broadband 20×20 microstrip antenna array is presented. Once a rectangular microstrip patch antenna with parasitic patches as an element antenna has been optimized at 24.2–26.7 GHz, a parallel‐series feed network with minimum feed lengths can be utilized to combine element antennas. From simulation and measurement, the array antenna yields relatively high gains of 26.0–30 dB and narrow 3 dB beamwidths of 4.5–5.1° in the H‐plane and 4.1–7.1° in the E‐plane, respectively, in an LMDS band. © 2002 John Wiley & Sons, Inc.
