摘要

提出了一种具有端馈串联馈电结构的低轮廓宽扇形波束高增益线性阵列天线。采用全向辐射磁流对传统微带天线、串联贴片天线和该天线进行了分析，并利用耦合狭缝环谐振器形成了宽扇形波束。该天线阵列由72Ω微带线和四个作为辐射元件的狭缝环谐振器组成。对该天线进行了制作和测量。实验结果表明，该天线的峰值增益为10.3 dB, e面半功率波束宽度为129°。该天线具有线性极化、宽扇形波束和高增益。

Series-Fed Slit Ring Resonator Antenna Array with Wide Fan-Beam and High Gain

A low-profile linear array antenna having an end-fed series-fed structure for high gain with a wide fan beam was proposed. The conventional microstrip antenna, a series-fed patch antenna, and the proposed antenna were analyzed with an omnidirectional radiating magnetic current, and a wide fan beam was created using a coupled slit-ring resonator. The antenna array consists of 72Ω microstrip lines and four slit-ring resonators acting as radiating elements. The proposed antenna was fabricated and measured. The proposed antenna has measured results, the peak gain is 10.3 dB, and the half-power beam-width(HPBW) of E-plane is 129°. The proposed antenna has linear polarization, a wide fan-beam, and high gain.
