Dual-band rectifier based on resistance compression networks

Abstract

This work presents the design of a dual-band rectifier operating at 915 MHz and 2.45 GHz with minimized sensitivity to input power and load variations. The rectifier is designed using a dual-band resistance compression network (RCN) for minimizing the effect of input power and load changes and it is based on Composite Right/Left-Handed (CRLH) to implement the dual band operation. The resulting rectifier has shown good RF-DC conversion efficiency and reduced sensitivity to variations.
