摘要： Embodiments of the invention comprise a system for improving subterranean RF signal propagation. Embodiments comprise a redirecting antenna element which includes a redirecting conductive arrangement, a feed point, and a receiving antenna element which includes at least one or more planes. The redirecting antenna element and receiving antenna are arranged to create a redirection of the energy produced by the existing RF device. Further, the proposed invention will cause the radio signal from the original RF device to be redirected to an elliptical propagation pattern. This new elliptical propagation pattern will be elongated from the original RF propagation pattern along an axis perpendicular to the neighboring streets and thus cause it to be intersected by drive-by reading systems at a greater distance when they intersect this axis.
