The paper proposes a simple four-element microstrip patch array antenna fed with corporate-series technique. The paper compares the proposed design with four-element antennas fed with only series-fed and corporate-fed microstrip antennas. All three antenna designs use rectangular microstrip patch elements with two insets and slots on both sides of the patch. The patch elements are accompanied by Yagi elements: three director elements and two reflector elements. Through comparison of simulation results, the paper shows that four-element array antenna with combined corporate-series feeding technique performs better compared to antennas with only either series or corporate feeding network. The proposed corporate-series fed antenna achieves better performance with wide frequency bandwidth of 25.04–30.87 GHz and gain of 9.5 dB. The antenna has an end-fire radiation pattern. Overall performance shows that the proposed corporate-series-fed microstrip patch antenna with Yagi elements is suitable for next generation 5G communication.

具有用于5G通信的企业系列馈电网络的四元素微带贴片阵列天线

本文提出了一种采用公司级系列技术的简单的四元素微带贴片阵列天线。本文将建议的设计与仅由串联馈电和企业馈电微带天线馈电的四元天线进行了比较。所有这三种天线设计均使用矩形微带贴片元件，在贴片的两侧均具有两个插入物和插槽。贴片元素与八木元素相伴：三个导向器元素和两个反射器元素。通过对仿真结果的比较，本文表明，与仅使用串联或公司馈电网络的天线相比，结合了公司串联馈电技术的四元件阵列天线的性能更好。拟议的公司系列馈电天线以25.04–30.87 GHz的宽频率带宽和9.5 dB的增益实现​​了更好的性能。天线具有端射辐射图。总体性能表明，拟议的带有Yagi元件的企业系列馈电微带贴片天线适用于下一代5G通信。
