Abstract

In this paper, a compact MIMO antenna with an electromagnetic bandgap structure is proposed for isolation enhancement. The proposed antenna design is coupled with an electromagnetic bandgap (EBG) structure to minimize mutual coupling between the antenna elements and to enhance the performance of the MIMO antenna configuration. The antenna is fabricated on an FR4 substrate having a dimension of (27.9×38×1.6 mm3). The EBG structure is analyzed, and the effect on antenna performance is studied using parametric analysis. The antenna is fabricated, and the measured results are compared with simulated ones. The antenna achieves a reduction in transmission coefficient |S21| ≥ 16 dB for simulated and |S21| ≥ 25 dB for measured results, and attains the minimum ECC of 0.09 which is very close to the ideal value of zero and hence makes it a better choice for MIMO applications.
