Abstract

In this paper, experimental verification of PTE (power transfer efficiency) enhancement is provided for a WPT (wireless power transfer) system consisting of circularly polarized (CP) transmitter and receiver antennas. The WPT system is first studied in three different realistic simulation environments. The PTE of the WPT system is enhanced by judicious use of a parasitic patch near the aperture of the implanted antenna (receiver). A low-cost experimental setup using software-defined radio (SDR), spectrum analyzer, fabricated antenna prototypes and skin-mimicking gel is implemented for the demonstration of PTE enhancement. © 2023 IEEE.
