Design of printed dipole antenna with reconfigurable radiation pattern

Peng Wang

Abstract

In order to obtain directional pattern and omnidirectional pattern in one antenna,a printed dipole antenna with reconfigurable radiation pattern is proposed in this paper. By controlling the states of the switches,the antenna can be operated as a monopole antenna with omnidirectional pattern or a dipole antenna with reflector of directional pattern. The effects of the antenna dimensions the antenna performance are analyzed using a commercial software package called Ansoft HFSS,and then the optimized parameters are presented. The antenna is fabricated and tested. The measured results are presented,which shows the bandwidth is 2.09～2.44 GHz at the switch off state and 2.64～2.94 GHz at the switch on state.
