1. A circular patch antenna, comprising:
a first dielectric patch comprising a first plurality of inner and outer feed apertures;
a top metallization positioned on top of the first dielectric patch;
a second dielectric patch comprising a second plurality of inner and outer feed apertures;
the first dielectric patch is positioned over the second dielectric patch;
wherein the first plurality of inner and outer feed apertures and the second plurality of inner and outer feed apertures are aligned with one another;
a middle metallization that is positioned between the first dielectric patch and the second dielectric patch, the middle metallization comprising a plurality of arc slots, each of the plurality of arc slots being positioned between the first and second plurality of inner and outer feed apertures and an external periphery of the middle metallization; and
a bottom metallization that is disposed below the second dielectric patch, the bottom metallization comprising a ground plane for the circular patch antenna.
