Abstract

This paper presents a Dielectric Resonator based dual frequency band Multiple Input and Multiple Output (MIMO) antenna for wireless communication. This antenna is designed for WLAN (5.55.8 GHz) and Xband (88.1 GHz) applications. A pair of DRAs is placed on a FR-4 substrate and is excited through microstrip feed lines placed on rear side of substrate. A via-less EBG structure is introduced to suppress the mutual coupling among DRAs. The measured isolation among the two antenna ports is 25 dB and 41 dB for 5.6 GHz and 8.05 GHz respectively. The overall dimension of the antenna is 0.72 λo × 0.52 λo at lower resonant frequency. Simulated and measured results are in good agreement, which supports the potential application of the proposed antenna for high gain WLAN and Xband applications.
