A Compact Dual Band-Notched MIMO Diversity Antenna for UWB Wireless Applications.

In this paper, a compact ultra-wideband (UWB) multiple-input multiple-output (MIMO) spatial diversity antenna with dual band-notches designed on an FR4 substrate is proposed and experimentally investigated. The antenna consists of two radiating elements fed by two tapered microstrip lines. Two inverted L-shaped slits are used to introduce notches at WLAN (5.15-5.85 GHz) and IEEE INSAT/Super-Extended C-band (6.7-7.1GHz). An isolation of more than 15 dB is achieved through the whole working band (2.9-10.8 GHz) by introducing a T-shaped decoupling structure on the ground plane. Furthermore, the envelope correlation coefficient (ECC), diversity gain (DG), multiplexing efficiency, TARC, peak gain and radiation patterns of theMIMO antenna are also discussed. The simulated and measured results show that the proposed UWB MIMO antenna is a good candidate for UWB diversity applications. [ABSTRACT FROM AUTHOR]
