1. An antenna configured to operate at millimeter wave frequencies, the antenna comprising:
a substrate comprising a first surface and a second surface;
a ground plane, wherein a first surface of the ground plane contacts the second surface of the substrate;
an active patch antenna element that defines a first corner, a second corner, a third corner, and a fourth corner, wherein the active patch antenna element is positioned on the first surface of the substrate, wherein the active patch antenna is configured to generate a radiation pattern;
a first parasitic patch element coplanar to the active patch antenna element, wherein a corner of the first parasitic patch element is adjacent to the first corner of the active patch antenna element;
a second parasitic patch element coplanar to the active patch antenna element, wherein a corner of the first parasitic patch element is adjacent to the second corner of the active patch antenna element;
a third parasitic patch element coplanar to the active patch antenna element, wherein a corner of the first parasitic patch element is adjacent to the third corner of the active patch antenna element;
a fourth parasitic patch element coplanar to the active patch antenna element, wherein a corner of the first parasitic patch element is adjacent to the fourth corner of the active patch antenna element;
a switching circuit configured to dynamically couple, to the ground plane, the first parasitic patch element, the second parasitic patch element, the third parasitic patch element, and/or the fourth parasitic patch element; and
a control circuit configured to control the switching circuit to dynamically couple the first, second, third, and/or the fourth parasitic patch elements to the ground plane based at least in part on one or more channel quality indicators (CQIs), wherein the one or more CQIs are indicative of a quality of connection between the antenna and one or more receiving entities, wherein the control circuit receives data over a single coaxial cable.
