Simulation results of the proposed microstrip patch antennas with the novel DPCS (a) S parameters showing improved isolation compared to the initial microstrip patch antennas, (b) E-plane of Port 1, (c) H-plane of Port 1, (d) E-plane of Port 2, (e) H-plane of Port 2, (f) surface current density of Port 1 for Port 1 excitation, and (g) surface current density for Port 2 excitation. The results demonstrate reduced mutual coupling and improved radiation patterns with the application of the DPCS.
