Wideband hexagonal‐shape stacked‐patch antenna array with L‐probe feed

Abstract

Abstract A two‐element hexagonal‐shape stacked‐patch antenna array fed by an L‐shaped probe is designed and measured. Experimental results show that the array achieves an impedance bandwidth of 34% (SWR < 1.5)/44% (SWR < 2) and a gain of 11.5 dBi. The far‐field radiation pattern is stable across the operation band. The antenna is attractive for modern mobile‐communications covering several frequency bands. © 2004 Wiley Periodicals, Inc.
