Abstract
According to one embodiment, a cover comprising a higher dielectric constant layer disposed outwardly from a lower dielectric constant layer is coupled to a rectenna operable to convert microwave power to electrical power. The cover receives microwave power, provides a substantial impedance match for a plurality of angles of incidence, and directs the microwave power to the rectenna. The impedance match is selected to broaden a receive pattern of the rectenna.
