摘要

本文提出了一种新型八木天线，它既具有谐振天线的紧凑性，又具有行波辐射体的宽带特性。它是用微带(MS)馈电在介质衬底上制备的。顶层由微带馈电、宽带微带-共面带状线(CPS)跃迁和两个偶极子元件组成，其中一个驱动元件由CPS馈电，另一个为导向元件。金属底部是一个微带接地，作为反射元件，并使用反射偶极子抵消。该天线采用低成本衬底，厚度为1.56mm， εr = 4.12。仿真带宽约为35%，增益大于5dB。

Designing Yagi-Uda antenna fed by microstrip line and simulated by HFSS

In this article, we have proposed a novel Yagi antenna that has both compactness of resonant antenna and broadband characteristics of traveling-wave radiators. It is fabricated on dielectric substrate with a microstrip (MS) feed. The top layer consists a microstrip feed, a broadband microstrip-to-coplanar stripline (CPS) transition and two diopole-elements, one of them which is driver element is fed by CPS, and the second is director. The metal underside is a microstrip ground which serves as a reflector element and cancels using reflector dipole. This antenna is constructed on low cost substrate with 1.56mm thickness and εr = 4.12. The simulated bandwidth is about 35% and its gain is more than 5dB.
