摘要
作者提出了一种腔背圆极化磁电（ME）天线的模式转换技术，以实现覆盖宽频率范围的宽轴比（AR）波束宽度。所提出的技术使 ME 天线元件和空腔结构参数相互独立，否则它们将始终相互关联。该天线的阻抗带宽为 38.73% (1.52-2.25 GHz)，3-dB 轴向比带宽为 33.05% (1.49-2.08 GHz)，3-dB AR 波束宽度在整个工作频带的单个平面（$xz$ 或 $yz/text{-plane}$）上超过 214°。
Circularly Polarized Cavity-Backed Antenna with Variable Magneto-Electric Crossed-Dipole Structure
The authors propose a mode conversion technique in a cavity-backed circularly polarized magneto-electric (ME) antenna in order to achieve a wide axial ratio (AR) beamwidth covering a wide frequency range. The proposed technique allows both the ME antenna element and the cavity structural parameters to be independent of each other, which would otherwise always be associated with each other. The proposed antenna demonstrated impedance bandwidth
$(\vert S_{11}\vert \leq-10\text{dB})$
of 38.73% (1.52-2.25 GHz), 3-dB axial ratio bandwidth of 33.05% (1.49-2.08 GHz), and 3-dB AR beamwidth exceeding 214° in a single plane (
$xz$
or
$yz\text{-plane}$
) across the operating band.
