Abstract

A rectenna includes (a) a multi-band multi-channel (MBMC) matching network, and/or (b) an adaptively reconfigurable rectifier or a breakdown-protected rectifier. An MBMC matching network includes a plurality of T-shaped transmission line matching structures coupled in series. An adaptively reconfigurable rectifier circuit includes a low input power rectifying portion, a high input power rectifying portion, and a set of transistors configured for selectively and automatically transitioning the adaptively reconfigurable rectifier between a low input power operating configuration and a high input RF power operating configuration, in a manner correlated with input RF power level. A breakdown-protected rectifier includes a transistor-protected diode structure having a diode coupled to a transistor in a manner that protects the diode from direct exposure to negative voltages that would ordinarily cause the diode to break down in the absence of the transistor.

Description

technical field [0001] Aspects of the present disclosure relate to methods for improving wireless performance through (a) multiband multichannel (MBMC) RF matching networks and / or (b) extended input power range rectifiers (which may include adaptively reconfigurable rectifiers or breakdown protection rectifiers). Rectenna circuit components, circuits and techniques for power transfer (WPT) or power conversion efficiency (PCE) in ambient RF energy harvesting circuits. Background technique [0002] Wireless power transfer (WPT) involves the transfer of RF power from a predetermined source or source of a specific type to a receive antenna coupled to a rectifier. The combination of a receiving antenna and a rectifier is called a rectenna. A rectenna converts received RF energy into DC power that can be used to power a system or device such as a sensor or medical instrument. Ambient RF energy harvesting involves harvesting RF energy that is inherent in modern environments due t...
