Superwideband Dual Notched Band MIMO Hexagonal Slot Antenna for Wireless Applications

Abstract

In this research article, a super-wideband monopole MIMO antenna with dual notched band characteristics is presented. Proposed antenna consist of compact volume of 20×35×0.787 mm ³ which is printed on Rogers RTDuroid5880 substrate (εr=2.2 & tanδ=0.0009). A hexagonal slot is introduced within the radiating patch on one plane of substrate and beveled ground on other side and is also capable of rejecting WLAN and Downlink Satellite System (DSS) interfering bands which are obtained by using inverted T-shaped stub and C-shaped parasitic element backed plane.. Proposed antenna offers good diversity MIMO characteristics in terms of ECC (Envelope Correlation Coefficient with ideal value ≤ 0.05), DG (Directive Gain, Ideal value ≥ 9.95dB) and TARC (Total Active Reflection Coefficient, Ideal Value ≤ -20dB). Proposed antenna also offers maximum gain of 5.95dBi, radiation efficiency of 91% and desired radiation pattern (dipole like pattern in E-plane and omni-directional pattern in H-plane).
