摘要

本文提出了一种低轮廓、宽带圆极化(CP)天线。它是由一个单馈交叉偶极子负载四个寄生补丁。由于寄生斑块的存在，天线在阻抗匹配和CP辐射带宽方面实现了低轮廓和宽带特性。最终设计的总体尺寸为120 mm × 120 mm 0╫16.3 mm (1.6 GHz时0.64λ0 × 0.64λ0 × 0.087λ0)，产生- 10 dB阻抗带宽为1.39-1.75 GHz (22.93%)， 3 dB轴比带宽为1.472-1.684 GHz(13.4%)，右侧CP宽增益> 8.4 dBic，辐射效率> 96%。

Low-profile crossed-dipole antenna loaded with parasitic patches

This paper presents a low-profile, broadband, circularly polarized (CP) antenna. It is composed of a single-feed crossed dipole loaded with four parasitic patches. Due to the presence of parasitic patches, the antenna achieves a low profile and a broadband characteristic in terms of impedance matching and CP radiation bandwidth. The final design, which has an overall size of 120 mm × 120 mm 0╫ 16.3 mm (0.64λ0 × 0.64λ0 × 0.087λ0 at 1.6 GHz), yields a −10 dB impedance bandwidth of 1.39–1.75 GHz (22.93%), a 3-dB axial ratio bandwidth of 1.472–1.684 GHz (13.4%), a right-hand CP broadside gain of > 8.4 dBic, and a radiation efficiency of > 96%.
