Abstract

Dual-polarized antennas are required in the current mobile communication to increase the channel capacity and reducing multi-path effects. Utilizing characteristic mode (CM) analysis, this paper presents a five-patch substrate integrated suspended line (SISL) antenna with suppressed unwanted higher-order modes, and achieves an enhanced bandwidth by using differential multi-point feeding (MPF) systems. Compared to single-point feeding systems, the proposed dual-polarized SISL antenna with the MPF system demonstrates a bandwidth 1.87 times wider. The novel SISL feeding system incorporates two pairs of differentially-fed branch line feed structures. A prototype of the proposed differential-fed antenna is fabricated and measured, showing good agreement between simulated and measured results. The dual-polarization SISL antenna can achieve realized gain from 8.1 dBi to 10.8 dBi within a working frequency from 3.17 GHz to 3.61 GHz (12.98%). Moreover, utilizing low-cost substrates, the proposed SISL antenna has the potential for 5G applications.

基于 CM 分析的差分多点馈电双极化 SISL 天线设计

目前的移动通信需要双极化天线来增加信道容量和减少多径效应。本文利用特征模态（CM）分析，提出了一种抑制了不需要的高阶模态的五贴片基底集成悬浮线（SISL）天线，并通过使用差分多点馈电（MPF）系统实现了带宽的增强。与单点馈电系统相比，采用 MPF 系统的双极化 SISL 天线的带宽扩大了 1.87 倍。新型 SISL 馈电系统包含两对差分馈电支线馈电结构。对所提出的差分馈电天线原型进行了制造和测量，结果显示模拟和测量结果之间具有良好的一致性。双极化 SISL 天线可在 3.17 GHz 至 3.61 GHz 的工作频率范围内实现 8.1 dBi 至 10.8 dBi 的增益（12.98%）。此外，利用低成本基板，所提出的 SISL 天线具有 5G 应用的潜力。
