Return coupled wireless power transmission
First Claim
1. A system, comprising:
- an excitation source;
a guided surface waveguide probe including a charge terminal elevated at a height over a lossy conducting medium and a feed network, the feed network being coupled between the excitation source and the charge terminal, the guided surface waveguide probe being configured to generate at least one resultant field that synthesizes a wave front incident at a complex Brewster angle of incidence of the lossy conducting medium; and
a conductor that extends a distance radially away from the guided surface waveguide probe across the lossy conducting medium.

Abstract
Aspects of return coupled wireless power transmission systems are described. In one embodiment, a system includes a guided surface waveguide probe including a charge terminal elevated at a height over a lossy conducting medium, and a feed network. The system further includes a conductor coupled to the guided surface waveguide probe that extends a distance away from the guided surface waveguide probe across the lossy conducting medium, and at least one guided surface wave receivers coupled to the conductor. The conductor can help to provide additional efficiency in power transfer between the guided surface waveguide probe and the guided surface wave receivers, especially when the operating frequency of the probe is in the medium, high, or very high frequency ranges.
