摘要

本文介绍了一种宽带差分馈电圆极化（CP）天线，其特点是具有大波束宽度的开槽贴片设计。差分馈电 CP 天线的最终设计旨在实现高增益和宽轴向比 (AR) 带宽，包括将差分弯曲偶极子天线耦合到同一平面上的开槽贴片。仿真和实验验证了所介绍的差分馈电 CP 天线具有大 AR 波束宽度的特点。在 5.5 GHz 时，xoz 平面（phi = 0°）和 yoz 平面（phi = 90°）分别测得 132.3° 和 116.2° 的 AR 波束宽度。测量结果具有宽带性能，-10 分贝阻抗带宽为 78.8%（3.81-8.76 千兆赫），3 分贝 AR 带宽为 36.7%（4.78-6.93 千兆赫），最大增益为 10.2 分贝。

A Wideband Differentially Fed Circularly Polarized Slotted Patch Antenna with a Large Beamwidth

A wideband differentially fed circularly polarized (CP) antenna featuring a slotted patch design with a large beamwidth is presented. The final design of the differentially fed CP antenna, aimed at achieving high gain and a wide axial ratio (AR) bandwidth, involves coupling a differential bending dipole antenna to the slotted patch in the same plane. The presented differentially fed CP antenna demonstrates characteristics of a large AR beamwidth, as verified by simulation and experiment. The measured AR beamwidths of 132.3° in the xoz plane (phi = 0°) and 116.2° in the yoz plane (phi = 90°) are realized at 5.5 GHz. The measured result exhibits broadband performance with a -10-dB impedance bandwidth of 78.8% (3.81–8.76 GHz), a 3-dB AR bandwidth of 36.7% (4.78–6.93 GHz), and a maximum gain of 10.2 dBic.
