AN MIMO F-SHAPED DIELECTRIC RESONATOR ANTENNA FOR 4G APPLICATIONS

A multiple input multiple output (MIMO) F-shaped dielectric resonator antenna (DRA) for mobile device is presented in this article. The F-shaped DRA is mounted on FR4 as a substrate. The measured impedance bandwidth for Port 1 is 36% (2.30-3.31 GHz) while Port 2 is 31% (2.30-3.14 GHz), respectively with isolation of -33 dB. Two orthognal modes are excited in this design which are TE1 delta 1y mode at Portl and TE delta 11x at Port 2. Correlation coefficient of a MIMO F-shaped DRA is 0.04 with diversity gain nearly 10 dB over operating frequency. The antenna provides gain 1.99 dBi for Port 1 and 1.85 dBi for Port 2 at frequency 2.6 GHz. The parameters, isolation, gain, correlation coefficient, and diversity gain of the MIMO rectangular dielectric resonator antenna are studied, and reasonable agreement between the measured and simulated results is observed.
