A Zero-Mode Induced mmWave Microstrip Patch Antenna with Ultra Wideband

Abstract

In this paper, a UWB (Ultra-Wideband) patch antenna with three shorting pins is proposed. The patch antenna contains three shorting pins that are loaded to generate extra modes, i.e., zero mode, thereby combining with other TM modes and realizing wide bandwidth. The simulated results show that the antenna has a wide relative bandwidth of 41.63% in the millimeter Wave frequency band from 23.95 GHz to 36.54 GHz with the antenna gain varying from 6.1 dBi to 7.0 dBi. Moreover, a $4\times 2$ array is also proposed and simulated. The size of array is 22.5 $\mathrm{m}\mathrm{m}\times 11.4$ mm and the maximum gain of array is 12.5 dBi.
