摘要
为实现天线的小型化,借助ADS2009电磁仿真软件,设计了一种1.8 GHz微带平衡巴伦馈电印刷偶极子天线。样机测试结果显示,该天线相对带宽为15.54%,增益为2.16 dB,输入阻抗为49.37+j1.605Ω,3 dB波瓣宽度为78.8°。实测特性阻抗、回波损耗特性、E面水平极化方向及H面垂直极化方向等电磁辐射性能与仿真结果基本相符。该天线可独立使用,或作为大型天线阵的辐射元。
This paper is an attempt to realize antenna miniaturization by designing 1.8 GHz printing dipole antennas with balanced balun microstrip feed by using ADS2009 electromagnetic simulation soft- ware. The test of the prototype antenna shows that the antenna has a relative bandwidth of the antenna of 15.54%, gain of 2.16 dB, input impedance of 49.37 ＋ j1. 605 Ω, and 3 dB lobe width of 78.8°. Elec- tromagnetic radiation performances, such as characteristic impedance, return loss characteristic, E plane horizontal polarization and H plane vertical polarization pattern, are found to be generally consistent with simulation results. The antenna can come into an independent use, or works as a large antenna array of radiating elements.
