摘要：

In this paper, the design of a closely spaced two-element ultrawide band (UWB) Surya Yantra shaped dielectric resonator antenna (DRA) array is presented. Novel rectangular loop-shaped defected ground structure (DGS) is introduced to reduce mutual coupling between DR elements. Fabrication and testing of the antenna array were carried out. Measured UWB of about 101% (3.1-9.4 GHz) was achieved. Mutual coupling below -15 dB is achieved over the entire band of interest using DGS. The proposed antenna array is a prominent candidate for MIMO applications due to its low mutual coupling, 101% UWB, the average gain of about 4.4 dBi, and fairly stable radiation pattern.
