A pattern reconfigurable DRA array for MIMO applications

This paper presents our study on the dielectric resonator antennas (DRA) to achieve pattern reconfigurability. The antenna array consists of two identical DRA placed at the center of two perpendicular planes. The antenna demonstrates radiation pattern reconfiguration in the 2.4 GHz frequency spectrum and therefore improves the channel capacity of a MIMO communication system. With 3 antenna modes in each DRA, the MIMO system can automatically select within 9 different pattern combinations to achieve optimum channel capacity at different receiver locations.
