摘要

本文研究了在无通孔基板集成波导漏波天线宽壁上刻蚀不同形状周期槽的影响。考虑了不同形状的槽，即圆形、椭圆形、矩形和三角形。在x波段频率范围内，对不同形状天线的增益、辐射效率和扫描范围进行了性能比较研究。几个结构被制造出来。50条Ω微带线用于激励天线。考虑到较高的增益、辐射效率和较宽的扫描范围(含阻带)，矩形槽是最佳选择。实测结果与仿真结果吻合较好。

A comparative study on substrate integrated waveguide periodic leaky wave antennas with differently shaped periodic slots

In this paper, effects of different shapes of periodic slots etched on the broad wall of a via-less substrate integrated waveguide leaky wave antennas are presented. Different shapes of the slots namely circular, elliptical, rectangular and triangular are considered. A comparative performance study based on gain, radiation efficiency and scan range of the antenna for the different shapes is studied over X-band frequency range. Several structures are fabricated. 50 Ω microstrip lines are used to excite the antennas. It is observed that the rectangular shaped slot is the best choice if higher gain, radiation efficiency and wide scan range including the stopband is considered. Measured results match well with simulated results.
