Abstract

A simple bowtie-shaped MIMO dielectric resonator antenna (DRA) resonating at 2.45 GHz with 75 MHz measured common bandwidth for both ports is presented in this paper for 2.40-2.48 GHz WIFI band applications. The MIMO characteristics are obtained by simultaneously exciting the TEδ21 modes by coaxial probe and TM22δ modes by coupled aperture feed in the DRA. Omni-directional radiation patterns are obtained in both principle planes, simulated and measured radiation patterns are found to be close to each other. Moreover, the proposed bowtie-shaped DRA is compact, exhibits high isolation (25dB) and relatively low correlation (0.0156) suggesting its suitability for the MIMO applications.
