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 (25 dB) and relatively low correlation (0.0156) suggesting its suitability for the MIMO applications.
