Abstract

In this paper a 5G compact antenna is investigated at 28 GHz. The structure is based on Quasi-Yagi antenna comprising a director, driver, and reflector. The SIW technology is utilized to feed the antenna because of its numerous benefits. The antenna array is designed and simulated and the S, E pattern, and H pattern are analyzed for both single-element and array antennas. Moreover, the effects of various parameters such as the number of stubs, the length of the director, the distance between the director and driver, the length of the driver, and the distance between the driver and reflector on S are studied. The HFSS and CST software are used for all analyses. Additionally, for the array antenna the effects of increasing the number of directors on S and antenna gain, change in antenna length, and variations in distances between elements are evaluated.

摘要

本文研究了一款28GHz的5G紧凑型天线。该结构基于准八木天线，包括一个引向器、一个辐射器和一个反射器。由于其诸多优点，采用了基片集成波导（SIW）技术为天线馈电。设计并模拟了天线阵列，分析了单天线元和阵列天线的S参数、E面方向图和H面方向图。此外，还研究了诸如短截线数量、引向器长度、引向器与辐射器之间的距离、辐射器长度以及辐射器与反射器之间的距离等各种参数对S参数的影响。所有分析均使用HFSS和CST软件。此外，对于阵列天线，评估了增加引向器数量对S参数和天线增益的影响、天线长度的变化以及元件之间距离的变化。
