摘要

为了获得宽带和高增益，提出了一种工作在s波段的平面印刷准八木天线元件和阵列。天线单元可分为馈电单元和辐射单元两部分。通过电磁仿真对天线主要参数对天线性能的影响进行了仿真研究，得到了天线单元的优化设计方案。此外，设计了基于准八木天线单元的二元阵列来提高增益。根据仿真结果制作了天线样机并进行了测量。实验结果表明，该天线单元可以工作在2.8 ~ 4.5 ghz，平均增益为5.5dBi。天线阵的工作频率范围为2.9-4.3GHz，平均增益为7.5dBi。该天线单元和阵列均具有宽带和高增益的优点，可广泛应用于无线通信系统中。

Research on Broadband and High-Gain Quasi-Yagi Antenna and Array

In order to obtain broadband and high-gain, a sort of planar printed quasi-Yagi antenna element and array, which operating in S-band, are proposed. The antenna element can be divided into two parts: the feeding unit and the radiation unit. Effects of major parameters on antenna performance are simulated and studied through electro-magnetic simulation, and the optimal design of the antenna element has been obtained. In addition, binary array based on the quasi-Yagi antenna element is devised to enhance the gain. Prototype antennas according to simulation results have been fabricated and measured. Experimental results show that the antenna element can operate at 2.8-4.5GHz, and the average gain is 5.5dBi. The operating frequency range of the antenna array is 2.9-4.3GHz, and the average gain is 7.5dBi. Both the antenna element and array have advantages of broadband and high-gain, which can be widely used in wireless communication system.
