Abstract
This paper intends to find out how to diminish the mutual coupling of closely spaced two-port antenna elements with a novel H-shaped EBG in the E-plane. The UWB MIMO antenna isolation is more than 20 dB in the entire operating frequency. The maximum isolation is up to 37 dB, obtained by the two-unit cell EBG placed between two CPW-fed antenna elements. Two-unit cell EBG is altering the current between radiating elements and enhancing up to 10 dB isolation. The proposed EBG decoupling MIMO antenna size is 35 mm × 22 mm and designed on the FR-4 substrate. The |S11| (in dB) varies from 3.4 to 10.4 GHz and covering most of UWB frequencies. This antenna has realized gain of more than 4 dB on a broader bandwidth with ECC and CCL under 0.01 and 0.35 bits/sec/Hz, respectively, across the entire 10 dB bandwidth.
