Abstract

By using a novel meta-resonator structure, a miniaturized, surface mountable, shared aperture, and hybrid electric/magnetic dipole pattern diversity antenna is proposed for Internet of things (IoT) applications. By exploring the shared electric (E-dipole) and magnetic dipole (M-dipole) structures, a novel T-shaped split-ring resonator (SRR) with even and odd modes is presented and studied by current distributions and equivalent circuits. Broadside and omnidirectional (monopole-like) patterns are achieved by exciting the M-dipole and E-dipole modes of the T-shaped SRR, respectively. To validate the proposed design, this shared aperture metamaterial-inspired pattern diversity antenna with a small size of $0.295 \lambda_{0}\times 0.0065 \lambda_{0}\times 0.115\lambda_{0}$ is fabricated and measured. The measured overlapped −10 dB bandwidth is from 3.40 GHz to 3.63 GHz (7.0%, covering the LTE B42 band) and the port isolation is greater than 23 dB. Both two modes achieve a good radiation efficiency better than −0.79 dB (>83.0%).

用于 6 GHz 以下应用的小型化共用电偶极子和磁偶极子、模式分集物联网天线

通过使用新型元谐振器结构，为物联网（IoT）应用提出了一种小型化、可表面贴装、共享孔径和电/磁混合偶极子模式分集天线。通过探索共享电偶极子（E-dipole）和磁偶极子（M-dipole）结构，提出了一种具有偶数和奇数模式的新型 T 形分裂环谐振器（SRR），并通过电流分布和等效电路对其进行了研究。通过分别激发 T 型分环谐振器的 M-偶极子和 E-偶极子模式，实现了宽边和全向（类单极）模式。为了验证所提出的设计，我们制作并测量了这种共享孔径超材料启发的图案分集天线，它的尺寸很小，仅为 0.295 \lambda_{0}\times 0.0065 \lambda_{0}\times 0.115 \lambda_{0}$ 。测得的重叠 -10 dB 带宽为 3.40 GHz 至 3.63 GHz（7.0%，覆盖 LTE B42 频段），端口隔离度大于 23 dB。两种模式都实现了优于-0.79 dB（>83.0%）的良好辐射效率。
