RF Power Conversion to DC Power with a Leaky Wave Antenna

Abstract

Methods and systems for converting RF power to DC power utilizing a leaky wave antenna (LWA) are disclosed and may include receiving RF wireless signals utilizing one or more LWAs in a wireless device, and generating one or more DC voltages from the received RF signals utilizing cascaded rectifier cells. 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 a spacing between conductive lines in the waveguides. The LWAs may be integrated in one or more integrated circuits, integrated circuit packages, and/or printed circuit boards. The packages may be affixed to one or more printed circuit boards and the integrated circuits may be flip-chip-bonded to the packages.
