Design of compact triple band-notched UWB MIMO antenna with TVC-EBG structure

摘要

In this editorial, a compact two element Ultra Wide Band Multiple Input Multiple Output (UWB MIMO) antenna with triple-band notch characteristics is presented. A single Two Via Compact Electromagnetic Band Gap (TVC-EBG) structure is used to achieve triple-band notches at WiMAX, WLAN, and X Band. An inverse L-shaped stub is inserted in the ground plane of the antenna to diminish mutual coupling amid antenna elements. Isolation and Envelope Correlation Coefficient (ECC) is less than -15 dB and 0.015, respectively. The diversity properties like Total Active Reflection Coefficient (TARC), Diversity Gain (DG) are less than -10 dB and greater than 9.95 dB respectively. The proposed antenna is designed using a low-cost FR4 substrate with overall dimensions of 21 x 36 x 1.6 mm(3).
