摘要

基于电偶极子与磁偶极子相结合的互补天线概念，提出了一种线极化衬底集成波导(SIW)腔背磁电偶极子天线。这种天线具有宽波束宽度的辐射模式。半功率波束宽度(HPBW)在e面为175°，h面为130°。此外，该天线具有约$0.03 \lambda_{0}$的低轮廓($\lambda_{0}$为中心工作频率的空间波长)，具有良好的跨阻抗带宽辐射性能，包括稳定的增益，两个主平面的对称单向辐射方向图，特别是极低的交叉极化。对天线进行了设计、制作和测量。实测结果与模拟结果吻合较好。

Low Profile SIW Cavity-Backed Magneto-Electric Dipole with Wide Beamwidth Radiation Patterns

Based on the complementary antenna concept of combining an electric dipole with a magnetic dipole, a linearly polarized substrate integrated waveguide(SIW) cavity-backed magneto-electric(ME) dipole antenna has been proposed. This antenna has wide beamwidth radiation patterns. The half-power beamwidths (HPBW) are 175° in E-plane and 130° in H-plane. Besides, the proposed antenna has a low profile of about $0.03 \lambda_{0}$ ($\lambda_{0}$ is the space wavelength at center operating frequency) with good radiation performances across the impedance bandwidth including a stable gain, symmetrically unidirectional radiation patterns in both of the two principal planes and especially, a significantly low cross polarization. The antenna is designed, fabricated and measured. Measured results show a good agreement with the simulated ones.
