摘要
E面膜片滤波器由于结构简单、高Q值、滤波特性好、设计精度高、易于批量生产等优点,在毫米波雷达系统中得到广泛应用。文中对E面膜片滤波器进行了理论分析,利用误差合成法以及数据模拟仿真,研究了Ka波段E面膜片滤波器中,膜片厚度、膜片安装、膜片长度在不同加工误差下,对滤波器系统性能S参数的影响,为其加工制造提供理论指导。
E-plane metal insert waveguide filter is widely used in millimeter-wave radar systems. A theoretical analysis is made of the E-plane metal insert waveguide filter. Through random error synthesis and numerical simulation, the influence of the plane thickness, length, and installation with different mismachining tolerance on the filter performance S parameters in Ka band E-plane filters is analyzed, which can serves as a theoretical guidance to the production of millimeter-wave E-plane metal insert filters.
