Abstract

In this paper, an EBG-inspired two element triple band-notched ultra wideband multi input multi output antenna is proposed. The antenna is fabricated with the overall size of 47\(\times \)38\(\times \)0.8 \(\textrm{mm}^3\) using low cost FR-4 epoxy substrate. Designing and simulation is carried out using Ansys HFSS software. Using single EBG structure, triple band notches at 3.3, 5.72 and 8.32 GHz are obtained satisfying WIMAX, WLAN and uplink satellite X-bands respectively. By inserting inverted L-shaped stubs on the ground plane, an improved isolation better than 25 dB is achieved throughout the UWB range. Surface current distribution and radiation pattern of proposed MIMO antenna in E-plane and H-plane are studied and discussed. Performance parameters such as ECC, DG, CCL, TARC and MEG are also investigated and found to be within the acceptable limits specified for diversity applications. Therefore UWB-MIMO applications wherein triple band-notched MIMO antenna with simplified design, compact size and improved isolation is desired, proposed MIMO antenna will out stand as strong candidature.
