Abstract
An apparatus for coupling a signal supply with an antenna including first and second elements. The signal supply delivers a signal to the antenna at a connection locus. The first element has a first edge and the second element has a second edge; the connection locus includes part of the first and second edges. The apparatus includes a first and second feed structure. The first feed structure extends a feed distance from the signal supply to the second edge and divides the first element into two lands in spaced relation with the first feed structure to establish a separation distance intermediate the first feed structure and the two lands. The second feed structure couples the signal supply with the first proximal edge. The separation distance establishes a signal transmission structure between the two lands and the first feed structure.
