摘要

本文提出了一种平面准八木天线的设计，能够实现高前后比(即FTBR > 34 dB)，高增益(即> 6.4 dBi)和相对宽的带宽(即高达近1 GHz)。该天线设计用于覆盖2.45 GHz ISM频段。天线的外形尺寸为69 × 64 × 1.575 mm3。该天线由5个导向元件、1个驱动偶极子和1个反射地平面组成。通过第一导向元件和驱动偶极子元件的强耦合，使宽带成为可能。为了达到上述性能标准，对天线进行了优化。这种天线对于需要高度定向辐射模式的应用非常有用，例如点对点通信和无线电力传输。在此基础上构建相控阵可以进一步增强该天线的辐射特性。

A planar wideband Quasi-Yagi antenna with high gain and FTBR

This paper presents the design of a planar Quasi-Yagi antenna capable of achieving high Front-to-Back ratio (i.e. FTBR > 34 dB), high gain (i.e. > 6.4 dBi) and relatively wide bandwidth (i.e. up to almost 1 GHz). This antenna is designed to cover the 2.45 GHz ISM band. The overall dimensions of the antenna are 69 × 64 × 1.575 mm3. The antenna is made up of 5 director elements, 1 driven dipole and a reflector ground plane. Wide bandwidth is made possible through the strong coupling of the first director element and the driven dipole element. The antenna is optimized in order to achieve the above mentioned performance criteria. This antenna can be very useful for applications requiring highly directive radiation patterns such as point-to-point communications and wireless power transfer. The radiation characteristics of this antenna can be further enhanced by building a phased array based on it.
