Abstract

In this paper, a compact MIMO antenna with DGS (defective ground surface) is proposed. The proposed DGS of
Rectangular shape is placed in ground plane. It’s offer a mechanism to improve antenna performance, reduce antenna
size and reduce antenna to antenna coupling on platforms. In this way, the performance parameters of MIMO antennas
can be further improved. The concept of DGS is also used to collectively enhance the impedance bandwidth of antenna. A
high bandwidth is achieved with S11≤-10dB and S21≤-18dB from 2.057 to 6.140 GHz is achieved. The analysis has been
done by using IE3D software based on method of moments (MOM). In this paper we also introduced the comparison of
performance parameters of two antennas proposed MIMO antenna with DGS structure with MIMO antenna using IE3D
software.
