摘要

本文介绍了一种新型宽缝隙透明圆极化天线。圆极化是通过使用一个宽的开槽s形环路与对角线修剪的边缘，两个独立的镜像u形槽与馈电位置在导电贴片的中心来实现的。导电氧化物AgHT-8被用作1.48 mm厚透明有机玻璃衬底上的补片(εr = 2.3, tan δ = 0.000379)。该天线工作在0.80 GHz ~ 1.05 GHz(~27.47%)频段，同一频段内轴向比(AR)小于3db。对该天线的反射系数、增益、轴比、辐射方向图等性能参数进行了数值分析，结果表明该天线作为光学透明CP天线适用于RFID应用。

Wide Slot Circularly Polarized Conductive Oxide-based Transparent Antenna Design for ISM Band RFID Applications

A novel wide slot transparent circularly polarized antenna is illustrated in this paper. Circular polarization is achieved by using a wide slotted S-shaped loop with diagonally trimmed edges, two separate mirrored U-shaped slots with feed location at the center of the conductive patch. Conductive oxide AgHT-8 is used as a feeding patch over a 1.48 mm thick transparent plexiglass substrate (εr = 2.3, tan δ = 0.000379). The antenna operates in the band spanning from 0.80 GHz - 1.05 GHz (~27.47%) with the axial ratio (AR) less than 3 dB within the same band. Numerical studies have been carried out to analyze the performance parameters of the antenna such as reflection coefficient, gain, axial ratio, radiation pattern and it has been observed that the results are satisfactory for RFID applications as an optically transparent CP antenna.
