Abstract

In this paper, we propose a high-gain circularly-polarized (CP) dual-band antenna array for UHF (902-928 MHz) and microwave band (2.4-2.5 GHz) RFID applications. The proposed antenna consists of dual-ring radiators excited through apertures as the basic element. A 2-by-2 array formed by sequentially-rotated configuration exhibited 8 dBic gain at UHF band and 10 dBic gain at microwave band. Very good CP performance with axial ratio less than 1 dB was achieved at both bands.
一种适用于RFID阅读器的高增益圆极化双频天线阵列
在本文中,我们提出了一种用于UHF (902-928 MHz)和微波频段(2.4-2.5 GHz) RFID应用的高增益圆极化(CP)双频天线阵列。该天线由双环辐射体作为基本单元通过孔径激励构成。由顺序旋转结构形成的2 × 2阵列在超高频波段获得8 dBic增益,在微波波段获得10 dBic增益。在两个波段均获得了良好的CP性能,轴比均小于1 dB。
