摘要

本文提出了一种适用于基站的新型宽带单元天线，该天线覆盖了现有蜂窝系统1.65 ~ 2.93 GHz的所有频段。该天线元件在整个频率范围内具有8.7±0.8 dBi的稳定增益。水平波束宽度至少为60度。该天线单元的性能完全满足宽带基站天线的要求。基于磁电偶极子的天线元件由两个±45度极化的双领结状偶极子组成。两偶极子的馈电平衡采用步进宽度变化，以获得更好的阻抗匹配，并且设计简单，适合批量生产。此外，偶极子的辐射体采用双领结形状，以提高阻抗带宽。

A Dual-Polarized Wideband Element Antenna for Base Station Application

This paper presents a novel wideband element antenna for base station application covering all frequency bands for existing cellular system from 1.65 to 2.93 GHz. The proposed antenna element has a stable gain of 8.7 ± 0.8 dBi over the entire frequency range. The horizontal beamwidth is at least 60 degrees. The performance of this antenna element is satisfied all requirements for expected wideband base station antennas. The antenna element based on magneto-electric (ME) dipoles consists of two double-bowtie shaped dipoles for two polarizations of ±45 degrees. The feeding baluns for the two dipoles have step-changed width to obtain better impedance matching, and they are simply designed for mass production. Besides, the radiators of the dipoles are double- bowtie shaped to enhance the impedance bandwidth.
