We propose a new rectifier for microwave wireless power transfer using a multilayer substrate filter as an output filter. First, we designed three and four layer substrate filters with a electromagnetic field simulator and obtained their filtering characteristics. Next, we applied each multilayer substrate filters designed above to an output filter of rectifier and simulated its rectification efficiency.
This paper demonstrates fundamental evaluation results of a C-band rectifier using Si substrate for HySIC application. Usage of the Si substrate is attractive for future integration with other mixed signal circuit. Because of large loss tangent of the Si substrate, applicability as a circuit substrate to the C-band rectifier is discussed. Two types of the rectifier, conventional printed circuit board...
This paper proposes a distributed reactance compensation technique, which is a useful approach for reduction of dielectric loss in a substrate of printed spiral coils. Distribution of lumped capacitors between coil windings reduces voltage fluctuations, and thus the strength of electric field, finally yielding lower dielectric loss. The usefulness of the proposed technique was verified by both simulation...
