The monopole pair with the decoupling component: (a) 3D schematic of the whole structure, (b) front view, (c) top view with decoupling component, (d) top view without decoupling component, and (e) metallic strip and clearance on GND. The geometries of the decoupling element, antenna and the clearance are noted in the figure.
