Compact dual-band pattern reconfigurable antenna using switched parasitic array

A compact dual-band pattern reconfigurable antenna using switched parasitic array is proposed for 2.4 and 5.8 GHz wireless MIMO applications. The proposed antenna is based on dual-band driven and parasitic radiators (PR) with RF switches. The PR performs as a reflector or a director by controlling R...

Description
Summary:A compact dual-band pattern reconfigurable antenna using switched parasitic array is proposed for 2.4 and 5.8 GHz wireless MIMO applications. The proposed antenna is based on dual-band driven and parasitic radiators (PR) with RF switches. The PR performs as a reflector or a director by controlling RF switches. The antenna is designed to provide nine radiation patterns in three states at the frequencies of 2.4 and 5.8 GHz bands, respectively. Two states realise eight radiation patterns in the horizontal plane. The measured peak gain of all radiation patterns ranges from 6.1 to 9.7 dBi. Another state generates omnidirectional radiation patterns in the horizontal plane and measured gains of around 4.0 and 7.5 dBi for 2.4 and 5.8 GHz bands, respectively.
