摘要

本研究提出一种用于环境射频能量收集应用的超宽带天线。该天线基于共面波导(CPW)传输线，并包含一个矩形槽作为天线收集器。所提出的天线采用进化设计过程来实现50 Ω CPW馈线在所需频带上的阻抗匹配。参数化研究了CPW元件与矩形槽尺寸的关系。然后将收集器天线连接到倍压器的初级整流电路，以检查信号特性。该天线覆盖ISM (Industry, Science, and Medicine) Wi-Fi 2.45 GHz和5 GHz频段，在2.45 GHz和5 GHz频段实现增益分别为3.641 dBi和4.644 dBi。它具有2.16 GHz ~ 6.32 GHz的较宽频率，覆盖了105%的超宽带分数带宽(FBW)。

A Co-Planar Waveguide Ultra-Wideband Antenna for Ambient Wi-Fi RF Power Transmission and Energy Harvesting Applications

This study proposes an ultra-wideband antenna for ambient radio frequency (RF) energy harvesting applications. The antenna is based on a co-planar waveguide (CPW) transmission line and incorporates a rectangular slot as an antenna harvester. The proposed antenna utilizes an evolutionary design process to achieve impedance matching of the 50 Ω CPW feeding line over the desired frequency bands. A parametric study investigates CPW elements and rectangular slot size. The harvester antenna is then connected to the primary rectifier circuit of the voltage doubler to examine the signal characteristics. The antenna covers the Industry, Science, and Medicine (ISM) Wi-Fi bands of 2.45 GHz and 5 GHz, achieving a realized gain of 3.641 dBi and 4.644 dBi at 2.45 GHz and 5 GHz, respectively. It exhibits a relatively broad frequency ranging from 2.16 GHz to 6.32 GHz, covering the ultra-wideband fractional bandwidth (FBW) of 105%.
