摘要

提出了一种具有非均匀横槽的低旁瓣基板集成波导漏波天线阵列。通过调整在SIW上蚀刻的辐射槽的长度，可以有效地降低设计的副瓣电平。设计了一种具有相同相位和幅度的相等输出的四路SIW功率分配器，用于4 × 1阵列的馈电。该阵列副瓣电平低至-28.4 dB，扫描角范围为36°，频率范围为2.2 GHz ~ 3.0 GHz。

Low-sidelobe non-uniform transverse slotted antenna array fed by substrate integrated waveguide

A low-sidelobe substrate integrated waveguide (SIW) leaky wave antenna (LWA) array with non-uniform transverse slots is proposed. By tuning the length of the radiating slot etched on the SIW, the sidelobe level of the design can be effectively reduced. A four-way SIW power divider with equal outputs of same phase and amplitude is designed to feed a four by one array. The proposed LWA array shows a low sidelobe level up to -28.4 dB and can scan within an angular range of 36° with frequency varying from 2.2 GHz to 3.0 GHz.
