1. An apparatus, comprising:
an antenna including:
a planar conductor having an aperture formed in a portion of the planar conductor;
a variable component that is coupled between a middle of the aperture and a side of the aperture, wherein the variable component provides a variable impedance value;
a fixed component that is coupled between the middle of the aperture and an opposing side of the aperture, wherein the fixed component provides a fixed impedance value; and
wherein in response to changing the variable impedance value to be non-equal to the fixed impedance value, a signal provided at the middle of the aperture is radiated by the antenna.
