A cross-shaped MIMO reconfigurable dielectric resonator antenna for GSM and LTE/UMTS applications
In this work a MIMO Reconfigurable Dielectric Resonator antenna (DRA) is proposed. The antenna comprises of a cross-shaped dielectric resonator, fed by two orthogonal probes. Adjacent to both probes, two rectangular micro strip patches are stacked to the walls of DRA to enhance the return loss and improve the impedance matching. Two C-shaped deformations are made on the ground plane. Four PIN-Diodes are located on the C-shaped deformations. Re-configurability is achieved when PIN-diodes are switched OFF or switched ON. The re-configurability is attained for two resonance frequencies. For the configuration I, the antenna resonates at 1.84 GHz but the overall bandwidth covers GSM 1900 MHz. For the configuration II, the antenna resonates at 2.08 GHz but the total bandwidth includes frequencies, which can be used for LTE/UMTS 2100 MHz applications. The antenna performance is analyzed in terms of simulated return loss, radiation pattern, diversity gain and envelope correlation function. Simulated results confirm that this reconfigurable MIMO system has promising values for the mentioned parameters.
