Abstract

Wireless power transfer (WPT) technology can facilitate battery-less and non-monitored operation for wearable devices. One core component in a WPT system is the rectenna, which integrates an antenna with a rectifier circuit. This paper discusses core factors including load impedance and received power level which will determine the rectenna topology. On this basis, a specific demonstration will be given based on a low-power bio-information monitoring platform. Co-simulations between CST Microwave Studio (CST) and Advanced Design System (ADS) are conducted for the purpose of realizing an optimal rectenna structure. Following the simulated predictions, 3D-printed rectenna prototypes have been fabricated and experimentally validated. A good agreement between simulation and measurements over several practical parameter sweeps successfully verifies the rectenna working performance.
