1. An antenna apparatus comprising:
an antenna substrate having a first surface and an opposite second surface, the antenna substrate including an antenna ground plane at the second surface;
an antenna element at the first surface of the antenna substrate;
a first radio frequency (RF) component attached to the second surface of the antenna substrate and including RF circuitry to adjust a signal communicated with the antenna element;
a second RF component attached to the second surface of the antenna substrate; and
a coplanar waveguide (CPW) interconnect coupling the first RF component to the second RF component and comprising a central conductor and first and second ground conductors on opposite sides of the central conductor, the central conductor having a profile within an opening in the antenna ground plane.
