Abstract

In this paper a compact dual-port Multiple Input Multiple Output (MIMO) Dielectric Resonator Antenna (DRA) with high isolation has been presented and discussed. The DR is fed by two probe feeds, one touching the side wall of the DR while the other is drilled in the middle of the DR. Both the ports are excited in orthogonal modes with the same resonance frequency in the DR, thus resulting in high isolation. The presented antenna is suitable to operate at LTE bands 7 and 38. The bandwidth achieved is 310 MHz and an isolation of +15 dB has been obtained. Besides, the Envelop Correlation Coefficient (ECC), and Diversity Gain (DG) has also been studied for the proposed antenna.
