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.
