摘要

本文针对无线局域网（2.4/5.3/5.8 GHz）和 WiMAX（3.5 GHz）应用提出了一种多频带圆极化天线。该天线由辐射贴片和反射金属地板构成。利用特性模式理论分析了贴片的模式，并根据这些结果对天线进行了优化。拟议天线的 -10 dB 阻抗带宽分别为 53.53% (2.4-4.15 GHz) 和 47.28% (5.25-8.5 GHz)。该天线在低频段辐射左旋圆极化，在高频段辐射右旋圆极化。该天线的最大增益为 10 dBic。

Multi-band circularly polarized antenna for WLAN and WiMAX applications based on characteristic mode theory

A multi-band circularly polarized antenna is proposed for WLAN (2.4/5.3/5.8 GHz) and WiMAX (3.5 GHz) applications. The proposed antenna is constructed of a radiation patch and a reflecting metal ground. Characteristic mode theory is utilized to analyze the modes of the patch and based on these results the antenna is optimized. The −10 dB impedance bandwidths of the proposed antenna are 53.53% (2.4–4.15 GHz) and 47.28% (5.25–8.5 GHz), respectively. The antenna radiates left-handed circular polarization in the lower band and right-handed circular polarization in the upper band. A maximum gain of 10 dBic is achieved for the proposed antenna.
