摘要

研究了一种基于部分介质填充和横槽的矩形波导的漏波天线。通过对槽内磁场的匹配来定义复传播常数。给出了速度因子与波导填充参数的关系。考虑了介质在波导中的位置对天线特性的影响。分析了辐射方向图。定义了方向图倾斜角、最佳天线长度和第一零波束宽度。

Velocity factor of leaky-wave antenna based on partially filled rectangular waveguide

A Leaky-wave antenna based on a covered rectangular waveguide with partially dielectric filling and transverse slots is investigated. The complex propagation constant is defined by matching of magnetic field in slots. A velocity factor dependences on the waveguide filling parameters are presented. The influence of the dielectric position in the waveguide on the antenna characteristics is considered. The radiation pattern is analyzed. A pattern tilt angle, an optimal antenna length and a first null beamwidth are defined.
