1. A ground plane comprising:

  • an insulating layer, having a surface with an outer perimeter and an inner perimeter, comprising;

    a central region consisting of the region of the surface within the inner perimeter; and

    a peripheral region consisting of the region of the surface between the inner perimeter and the outer perimeter;

    a conductive layer having a thickness T, the conductive layer comprising;

    a first conductive segment disposed on the entirety of the central region;

    a second conductive segment disposed on the peripheral region and in electrical contact with the first conductive segment;

    a third conductive segment disposed on the peripheral region and spaced apart from the first conductive segment and from the second conductive segment; and

    a plurality of grooves in the conductive layer, each groove of the plurality of grooves having a thickness equal to the thickness T of the conductive layer;

    a lumped circuit element disposed within a particular groove of the plurality of grooves and electromagnetically coupled to the second conductive segment and to the third conductive segment;

    wherein;

    the outer perimeter is configured as a first circle with a first radius;

    the inner perimeter is configured as a second circle with a second radius, wherein the second circle is concentric with the first circle and the second radius is less than the first radius;

    the second conductive segment is configured as a first annular ring with an inner radius and an outer radius, wherein the first annular ring is concentric with the first circle and the inner radius of the first annular ring is equal to the second radius and the outer radius of the first annular ring is greater than the inner radius of the first annular ring and less than the first radius; and

    the third conductive segment is configured as a second annular ring with an inner radius and an outer radius, wherein the second annular ring is concentric with the first circle and the inner radius of the second annular ring is greater than the outer radius of the first annular ring and the outer radius of the second annular ring is greater than the inner radius of the second annular ring and less than or equal to the first radius.
