| 摘 要： | 提出了一种平衡微带线馈电的宽带印刷型八木天线,该天线具有剖面低、带宽宽、馈电简单的优势。使用CST Microwave Studio软件分析了天线的金属表面电流,建立了与天线辐射特性等效的对称振子阵列模型,解释了天线的辐射原理。根据仿真分析结果制作了天线样机并进行了测试,该天线可以在1.62~2.35 GHz的频率范围内满足反射系数低于-10 dB。在工作频率范围内的增益约为5 dBi,其尺寸仅为100 mm×38.5 mm×1 mm,可以应用于无线通信领域。

| Abstract: | This paper presents a wideband Yagi-Uda antenna (also called Yagi-antenna) fed by balanced microstrip with features of low profile, wide bandwidth and simplified feeding. With CST Microwave Studio?, the researchers analyzed the current on the metal surface of the antenna, based on which a symmetrical-dipole-array model is built. With the equivalent radiation characteristics, this model well explained the working principal of the proposed antenna. According to the results of simulation analysis, the authors make and test a prototype antenna. This prototype antenna has a reflection coefficient less than -10dB within the frequency range of 1.62~2.35GHz. In addition, this antenna has a gain of around 5dBi within its operating frequency range, with a size of only 100mm×38.5mm×1mm. It is an antenna which can be widely applied in wireless communication. |
