摘要:

分析并设计了一种双频水平极化全向天线,该天线采用印刷偶极子组阵形式实现全向辐射性能,采用双辐射臂形式以及梯形渐变线馈电,实现在2.4~2.5 GHz和5.1~5.9 GHz上回波损耗低于-10 dB的双频特性。低频增益1.2 dB,不圆度为0.2 dB;高频增益2.4 dB,不圆度为2 dB。该天线结构简单,拥有良好的全向性。

关键词: 水平极化, 全向天线, 双频

Abstract:

This paper analyzes a dual-band omni-directional antenna with horizontal polarization.A group of printed dipole antenna is used for omni-directional radiation.Double radiation arm and trapezoidal feed line are used to realize dual-band in 2.4~2.5 GHz and 5.1~5.9 GHz with return loss of generally less than -10 dB.The gain in low frequency is 1.2 dB,and its un-roundness is 0.2 dB.The gain in high frequency is 2.4 dB,and its un-roundness is 2 dB.The antenna has simple structure and good omnidirectivity.

Key words: horizontal polarization;omni-directional antenna;dual band
