Abstract

In this work, a symmetric pillbox antenna with low side lobes is designed, simulated and fabricated by using gap waveguide technology. The proposed antenna operates on the basis of the reflector antenna principle and provides a fan-beam radiation pattern. In the proposed structure, the antenna aperture is loaded by a stepped discontinuity and a corrective pin to improve the side-lobe level (SLL) and gain. The designed antenna impedance bandwidth (S₁₁ < −10 dB) is 42% at the Ku band. Also, −15 dB < SLL < −10 dB and a gain of 16.6–18.7 dBi are achieved over the operating bandwidth. There is a good agreement between the simulated and measured results.

隙波导技术中宽带低边瓣对称弹盒天线的研制

本文采用间隙波导技术，设计、模拟和制作了一种低侧瓣对称碉堡天线。所提出的天线基于反射天线原理工作，并提供扇形波束辐射方向图。在该结构中，采用阶梯式不连续和校正引脚加载天线孔径，以提高旁瓣电平和增益。设计的天线阻抗带宽(S11 <−10 dB)在Ku波段为42%。−15 dB <SLL & lt;−10db，工作带宽增益为16.6 ~ 18.7 dBi。模拟结果与实测结果吻合较好。
