摘要

本文提出了一种紧凑，频率可重构的磁电偶极子（MED）天线，具有孔径耦合激励，适用于5G （n77, n78, n79）和ISM/WLAN （2.4 GHz）应用。在1 mm厚的FR4基板上，该设计实现了优于85%的效率和60 × 60 × 12 mm3的占地面积。在本研究中使用了三个PIN二极管，这使得它可以在4种工作模式下动态调谐，提供2.30-5.50 GHz的宽带阻抗范围，并具有20 dB的良好对隔离。优化的相位设计带来了更好的性能，增益在6.70和7.05 dBi之间变化，稳定性更好。其具有成本效益的模块化使该天线比其他不可重构的替代方案更适合部署在5G、物联网和汽车通信等先进网络中。

A compact frequency-reconfigurable magneto-electric dipole antenna with aperture-coupled excitation for 5G and ISM/WLAN applications

This paper presents a compact, frequency-reconfigurable magneto-electric dipole (MED) antenna with aperture-coupled excitation for 5G (n77, n78, n79) and ISM/WLAN (2.4 GHz) applications. At a 1 mm-thick FR4 substrate, the design achieves a better than 85% efficiency and a footprint of 60 × 60 × 12 mm³. Three PIN diodes are used in this study, which makes it dynamically tunable across 4 modes of operation, giving a broadband impedance range of 2.30–5.50 GHz with good pair isolation of 20 dB. Optimized phases in the design lead to better performance with gains varying between 6.70 and 7.05 dBi and better stability. Its cost-effective modularity makes this antenna more appropriate than other non-reconfigurable alternatives for deployment in the advanced networks such as 5G, IoT, and automotive communications.
