摘要

本文提出了一种适用于GSM1800/3G/LTE/5G室内通信系统的宽带低交叉极化全向天线。该天线采用沿中心均匀排列的打印对数周期天线单元，实现了全向辐射方向图。此外，在对数周期天线和环形寄生贴片的配合下，可以同时获得较宽的带宽和良好的全向辐射性能。仿真结果表明，在整个工作频率增益约为1.5 dBi的情况下，阻抗带宽为1.7 ~ 3.8 GHz(76.4%)。还获得了小于- 30 dB的低交叉极化电平和紧凑的尺寸。

A Wideband Omni-directional Antenna Based on Printed Log-Periodic Element

In this paper, a novel omni-directional antenna with wideband and low cross-polarization for GSM1800/3G/LTE/5G indoor communication systems is proposed. By using the printed log-periodical antenna elements, which are evenly arranged around the center, the proposed antenna achieves the omnidirectional radiation patterns. Moreover, with the cooperation of the log-periodical antenna and the annular parasitic patches, a wide bandwidth and a good omnidirectional radiation performance are achieved simultaneously. Simulated results indicate that an impedance bandwidth of 1.7-3.8 GHz (76.4%) can be achieved with a gain of approximately 1.5 dBi across the whole operating frequency. Low cross-polarization level of less than −30 dB and compact size are also acquired.
