Pattern reconfigurable antenna using key-shaped monopoles for WiMAX application

Abstract

In this paper, omnidirectional pattern reconfigurable antenna is designed using key-shaped monopole antennas. It consists of two identical key-shaped monopoles with partial ground plane. The proposed antenna provides pattern reconfigurability in the two different planes YZ and XZ with the help of two PIN diodes. The overall dimension of the proposed antennas is 40x40x1.6 mm3. It covers the 10dB impedance bandwidth of 64.32% (2.88 to 5.61 GHz), which covers a wide range of applications. © 2019 URSI. All rights reserved.
