Simulated 3D radiation patterns when both Port1 and Port2 are fed on the (a) x-axis, (b) y-axis, and (c) z-axis for the base antenna at 3.60 GHz; on the (d) x-axis, (e) y-axis, and (f) z-axis for Ant.1 at 3.55 GHz; on the (g) x-axis, (h) y-axis, and (i) z-axis for Ant.2 at 3.70 GHz; and, finally, on the (j) x-axis, (k) y-axis, and (l) z-axis for Ant.3 at 3.34 GHz.
