Abstract

In this paper a high efficiency, low-cost and low-complexity RF-DC converter was designed at 2.4 GHz that maintains increased efficiency range for a wide range of incident angles. The circuit of converter is based on a Wilkinson power combiner with two single-diode rectifiers. The proof of concept prototype uses a single-diode rectifier instead of the isolation resistor for recycling the wasted power when the input signals do not have the same phase. The modified Wilkinson power combiner was fabricated and measured using commercially available components. The measured rectifier RF-to-DC efficiency was 19.7% for in-phase input signals with power -20 dBm. Measurement results also showed that when the relative phase of input signals varied from 90 to 360 degrees, a variation in efficiency between 15% and 20.7% was observed.
