Abstract
An apparatus for conveying electromagnetic energy intermediate a host device and a medium substantially adjacent to the apparatus includes: (a) a transceiver for transmitting the energy to and receiving the energy from the medium; (b) a transmission structure for conveying signals to or from the host device; and (c) a feed structure coupling the transceiver with the transmission structure. The transceiver includes a planar metal layer arrayed upon a dielectric substrate. The metal layer is bounded by a first edge and a second edge. The first and second edges cooperate to form a bight having a first and a second arm establishing a metal-free area intermediate the first and second arms. The first arm presents a first terminal locus and the second arm presents a second terminal locus. The feed structure is coupled with the first and second terminal loci to effect the coupling.
