Abstract:
1. A current collector, which comprises: a) a frame comprising at least one frame conductor providing a closed perimeter; b) a plurality of first radiating conductors radiating from a focal point on the frame and terminating at the frame perimeter spaced from the focal point; c) a first group of at least two first concentric conductors being concentric with the focal point, the first group of concentric conductors extending from and meeting with spaced apart first and second frame portions of the frame perimeter and intersecting the plurality of radiating conductors; d) a second group of at least two second concentric conductors being concentric with the focal point, the second group of concentric conductors extending from and meeting with spaced apart third and fourth frame portions of the frame perimeter and intersecting the plurality of radiating conductors; and e) wherein from the focal point to an outer most one of the first concentric conductors is a distance “x” and from the focal point to a nearest most one of the second concentric conductors is from about 1x to about 10x, and wherein there are no concentric conductors intermediate the outer most one of the first concentric conductors and the nearest most one of the second concentric conductors.
