1. An antenna, comprising:

  • a first ground element;

    a first driven element formed from a planar piece of conductive material, the first driven element being configured to transmit and receive wireless signals, the first driven element including a physical slot;

    a conductive line formed in the physical slot such that the conductive line is separated from the first driven element by a gap filled with non-conductive material, the conductive line having a line impedance that is a function of an effective line width of the conductive line, and an effective gap width of a gap between the conductive line and the first driven element; and

    a signal line configured to send and receive signals to and from the conductive line.
