Method and system for power transfer utilizing leaky wave antennas
View Patent ↗Methods and systems for power transfer utilizing leaky wave antennas (LWAs) are disclosed and may include configuring one or more LWAs in a communication device to receive RF signals that are communicated from one or more other LWAs that are external to the communication device. The communication device may be powered utilizing the RF signals that are received via the configured LWAs. A resonant frequency of the LWAs may be configured utilizing micro-electro-mechanical systems (MEMS) deflection. The LWAs may be configured to receive the RF signals from a desired direction. The LWAs may comprise microstrip or coplanar waveguides, wherein a cavity height of the LWAs is dependent on spacing between conductive lines in the waveguides. The LWAs may be integrated in integrated circuits, integrated circuit packages, and/or printed circuit boards. The packages may be affixed to printed circuit boards and the integrated circuits may be flip-chip-bonded to the packages.
