Design of UWB MIMO Antenna to Reduce the Mutual Coupling Using Defected Ground Structure

Abstract

A novel compact monopole UWB antenna is described and analyzed using defect in ground plane (DGS). This MIMO design has an area of 60 × 35 mm2 with total size of 2100 mm2 which maintained between the square type patches seperation is 0.05 λ0. The current design achieved tri-band frequencies at 3.5, 4.8 and 9.0 GHz due to introducing arcs at the edges of square type patches. For the impedance bandwidth of the design covers an average peak gain of radaitor is 5.04 dBi with a little-bit variations in the current design is ± 1.20 dBi. The measured Impedance Bandwidths of the MIMO design are 1000 MHz (3.0–4.0 GHz), 1300 MHz (4.3–5.6 GHz) and 1100 MHz (8.4–9.5 GHz) covered the frequency range from 2.0 to 10.0 GHz. These frequencies covered the applications of WLAN, bluetooth and ultra-wide band which maintained VSWR ≤ 2. The proposed structure resembles a omnidirectional radaition patternswith narrow compact sizeat the resonant band of frequencies.
