Abstract

A compact system design for simultaneous wireless information and power transfer (SWIPT) based on a novel symbol-splitting (SS)-technique is proposed in this letter. A rat-race coupler is adopted between the receiving terminal and the rectifier to facilitate the separation and isolation of the noninformation-carrying components of the received signal from the information-carrying components for rectification and data recovery, respectively. The maximum conversion efficiency of the design reaches over 60% with -4-dBm input power and remains around 50% down to input powers of -10 dBm in measurements using both continuous-wave (CW) signals and modulated signals with different data rates as inputs. The transferred data are correctly received and recovered at the isolation port of the coupler. The design is 51.7×49.3 mm 2 , and all measurement results show good agreement with the simulation results.
