Abstract

This article proposes a broadband circularly polarized (CP) magnetoelectric (ME) dipole antenna for millimeter-wave (mmW) communications. Based on a conventional linearly polarized ME-dipole, a pair of centrally symmetric L-shaped strips generates a rotating electric field with a 90° phase difference for CP radiation. A microstrip line feeds the antenna via a center-symmetrical matching branch on a coupling slot. A parasitic top layer enhances bandwidth, achieving 26.9% impedance bandwidth (|S₁₁| < −10 dB), 20.8% 3-dB axial ratio (AR) bandwidth, and 8 dBic peak gain for the element. A fabricated 4 × 4 array using these elements with sequential rotation technique (SRT) feeding shows good agreement between simulation and measurement: 30.7% impedance bandwidth, 26.5% 3-dB AR bandwidth, and 15 dBic peak gain. The design offers superior CP performance, low profile, and high integration for millimeter-wave systems.

毫米波通信用宽带圆极化磁电偶极天线

提出了一种用于毫米波通信的宽带圆极化磁电偶极子天线。在常规线极化me偶极子的基础上，一对中心对称的l形条带产生CP辐射相位差为90°的旋转电场。微带线通过耦合槽上的中心对称匹配分支馈送天线。寄生顶层增强了带宽，实现了26.9%的阻抗带宽（|S11| <−10 dB）， 20.8%的3 dB轴向比（AR）带宽和8dbic峰值增益。利用这些元件和顺序旋转技术（SRT）馈电制作的4 × 4阵列在模拟和测量之间表现出良好的一致性：阻抗带宽为30.7%，3-dB AR带宽为26.5%，峰值增益为15 dBic。该设计为毫米波系统提供了卓越的CP性能、低姿态和高集成度。

期刊介绍： Science has many big remaining questions. To address them, we will need to work collaboratively and across disciplines. The goal of iScience is to help fuel that type of interdisciplinary thinking. iScience is a new open-access journal from Cell Press that provides a platform for original research in the life, physical, and earth sciences. The primary criterion for publication in iScience is a significant contribution to a relevant field combined with robust results and underlying methodology. The advances appearing in iScience include both fundamental and applied investigations across this interdisciplinary range of topic areas. To support transparency in scientific investigation, we are happy to consider replication studies and papers that describe negative results. We know you want your work to be published quickly and to be widely visible within your community and beyond. With the strong international reputation of Cell Press behind it, publication in iScience will help your work garner the attention and recognition it merits. Like all Cell Press journals, iScience prioritizes rapid publication. Our editorial team pays special attention to high-quality author service and to efficient, clear-cut decisions based on the information available within the manuscript. iScience taps into the expertise across Cell Press journals and selected partners to inform our editorial decisions and help publish your science in a timely and seamless way.
