摘要

本文设计了一种宽带双极化多谐振天线。该天线由主辐射器、集成平衡器和反射器组成。与传统的平衡馈电双极化天线不同，集成平衡天线通过在地面蚀刻槽产生额外的谐振模式。在不增加天线尺寸或改变偶极子形状的情况下，有效地扩展了天线的带宽。天线的设计和仿真都很好。仿真结果表明，该天线具有约70%的极宽阻抗带宽(1.64-3.39 GHz)，驻波比小于1.7，两个端口之间的隔离度大于25 dB。此外，该天线的稳定增益在8.7±1.5 dBi范围内，半功率波束宽度在60°±8°范围内。

A Broadband Dual-Polarized Multi-Resonance Antenna for Base Station Applications

A broadband dual-polarized multi-resonance antenna is designed in this paper. The antenna is composed of the main radiator, integrated baluns, and reflector. Different from the traditional balun-fed dual-polarized antenna, an additional resonant mode is produced by etching slot on the ground of the integrated balun. The bandwidth of the antenna is effectively expanded without increasing the antenna size or changing the shape of the dipole. The antenna is well invented and simulated. The simulated results confirm that the antenna has a very wide impedance bandwidth (1.64-3.39 GHz) of about 70% with VSWR less than 1.7, and the isolation between the two ports is greater than 25 dB. In addition, the proposed antenna has a stable gain within 8.7±1.5 dBi and the half-power beamwidth within 60°±8° in the operating band.
