Abstract

This paper introduces a newly designed X-shaped slot antenna with high gain and wideband characteristics for use in mm-wave frequency band. The X-shaped slot antenna serves as radiating elements of planar array configuration for high gain. The 4×4 configuration is investigated in this paper. According to simulation results, the 4×4 planar array exhibits a −9.7 dB impedance bandwidth within the range of 26.1-31 GHz and a maximum gain of 18.2 dBi. Furthermore, gain and bandwidth enhancement of the array antenna is studied. As the results, the antenna shows an impedance bandwidth within the range of 25.35–25.95 GHz, and 26.8–30.2 GHz. Within this band the antenna realized gain is ranging from 17.5–20 dBi.
