Abstract:
1. An antenna configured to generate a uniform distribution of an electrical field, the antenna comprising: a substrate formed from a dielectric material, the substrate having a first surface opposite a second surface; a plurality of feed lines, each of the plurality of feed lines extending along an axis from a first end of the substrate to a second end of the substrate; and an antenna array disposed on the first surface of the substrate, the antenna array proximately coupled to the feed line, the antenna array having a plurality of resonating lines, each of the plurality of resonating lines having a first resonating end spaced apart from a second resonating end, and a center resonating portion disposed between the first and second resonating ends, each resonating lines having a plurality of resonators axially aligned and each of the resonating lines is aligned along the axis of a corresponding feed line in the plurality of the feed lines, each of the plurality of resonators having a resonating surface, the resonating surfaces are larger at the first and second resonating ends than the resonating surfaces in the center resonating portion of the resonating line so as to produce a smaller electric field in the center of the substrate resulting in a generally uniform electric field throughout the substrate and along the respective feed lines.
