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 mm3 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).

无线应用的超宽带双陷波带MIMO六角形槽天线

本文提出了一种具有双陷波带特性的超宽带单极MIMO天线。所提出的天线体积为20×35×0.787 mm3，打印在Rogers RTDuroid5880衬底上(εr=2.2 & tanδ=0.0009)。在基片的一侧平面的辐射贴片和另一侧的斜面地面内引入六角形槽，并且能够抑制由倒t形存根和c形寄生元件背平面获得的WLAN和下行链路卫星系统(DSS)干扰带。该天线在ECC(包络相关系数理想值≤0.05)、DG(指示增益，理想值≥9.95dB)和TARC(总主动反射系数，理想值≤-20dB)方面具有良好的分集MIMO特性。该天线的最大增益为5.95dBi，辐射效率为91%，具有理想的辐射方向图(e面类偶极子方向图和h面全向方向图)。
