Radiation Pattern Reconfigurable MIMO Antenna with EBG for Improved Steering Performance

This paper presents a radiation pattern reconfigurable (RPR) multiple-input-multiple-output (MIMO) antenna with an electromagnetic band gap (EBG) for improved steering performance. The designed RPR-MIMO operates at 3.5 GHz with S

< −10 dB, S

< −15 dB, steered angle of more than 19° and a minimum average gain of 5 dBi at all steered directions. The proposed EBG structure improved the steering angle that is affected when the RPR is deployed as the MIMO.
