Wire-bonds used as matching inductor in RF energy harvesting applications

This document presents an alternative antenna matching strategy for RF Harvesting circuits, based on the use of wire-bonds as external matching inductors. In the following, the electrical characteristics of the bond-wires are evaluated in terms of inductance, quality factor and UHF behavior. Pad de-embedding techniques are applied to reduce parasitic influence. A HFSS model is built as well in order to provide a predictive tool for further improvements. The measurements and simulations are compared and a real-case application is presented.
