Patch antenna design for easy fabrication and controllable performance at high frequency bands

A radiator for an antenna, comprising:

• a pair of PCB stems arranged in a cross fashion, each of the PCB stems having:
• a front side and a rear side, wherein disposed on each PCB stem front side is a pair of feeder metallic traces, wherein each feeder metallic trace comprises a feeder portion and a horizontal trace portion such that the horizontal trace portion is perpendicular to the feeder portion, wherein disposed on each PCB stem rear side is only a corresponding pair of opposing horizontal metallic traces having a profile that substantially overlaps a profile of a corresponding horizontal trace portion on the front side of the PCB stem, wherein each horizontal trace portion on the front side of the PCB stem and its corresponding opposing metallic trace on the rear side of the PCB stem is electrically coupled by at least one via formed in the PCB stem and disposed along the horizontal trace portion, wherein each feeder portion on the front side of the PCB stem is configured to couple to a radio frequency (RF) source;
• and
• a radiator plate comprising a cross-shaped aperture for mechanically mounting the radiator plate to the PCB stems and mechanically coupled to the pair of PCB stems, via the cross-shaped aperture;
• wherein the at least one via comprises a plurality of vias disposed between the horizontal trace portion and the corresponding opposing metallic trace.
