摘要

本文提出了一种新型的圆极化发射天线，用于具有极化分离的同时无线信息与电力传输系统。与SWIPT中传统的功率和信息分离方法相比，极化分离更具实用性和灵活性。基于这种分离结构，我们在系统发射部分设计了一种新型圆极化(CP)天线。该天线具有宽带工作范围。天线的最终设计总体尺寸为35。5mm x 35.5mm x 34.7mm。阻抗带宽为51% (2.09 ~ 3.51 GHz)，轴比带宽为53%(2.39 ~ 4.14GHz)。在工作频带上，天线获得约8dBi的稳定增益。该天线能够同时满足信息传输和功率传输的要求。

A Novel Circular-Polarized Antenna for SWIPT System with Polarization Separation

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.
