Abstract
This article presents a new circular-polarized transmitting antenna for a simultaneous wireless information and power transfer (SWIPT) system with polarization separation. Compared to the traditional power and information separation approaches in SWIPT, the polarization separation is more practical and flexible. Based on this separation architecture, we design a novel circular-polarized (CP) antenna in the transmitting part of the system. The antenna has the wideband operation range. The final design of the antenna has an overall size of 35. 5mm x 35.5mm x 34.7mm. In addition, the impedance bandwidth and axial ratio (AR) bandwidth are 51 %(2.09-3.51 GHz) and 53%(2.39-4.14GHz). Over the operating band, the antenna obtains stable gains for around 8dBi. The antenna is able to satisfy the demands of information and power transfer simultaneously.
