An antenna architecture containing a broadband resonant cap positioned over a radiating patch is disclosed. The resonant cap consists of a rectangular resonant patch at the center with parasitic patches in close proximity of the four edges of the resonant patch. The parasitic patches may be coplanar with the resonant patch or may be mounted at an angle with respect to the vertical axis of the resonant patch. The resonant cap reduces the HPBW of the emitted radiation and improves emission directivity.
