Abstract: A novel stacked double U, angular ring shaped MIMO antenna is designed using DGS, and a pair of balanced shorting pin is proposed for C, X, and K-band applications. The aim of this design is to enhance the bandwidth by using different techniques in a compact MSA. The proposed antenna is designed on an FR4 substrate with permittivity of 4.4 is used in this design with dimension of 10×10 mm2 with two-microstrip line and one coaxial feed as a feeding mechanism. Two asymmetrical antennas of FR4 substrate are stacked with an air gap of thickness 1.6mm that exhibits a low correlation coefficient; low mutual coupling and refection coefficient is below-25 dB. The antenna is simulated through HFSS software 13.0 version shows Operates at UWB of frequency range 6.17-9.3, 18.1-18.7 GHz with maximum radiation efficiency of 83%.
