摘要
针对目前一般的E面金属双膜片波导滤波器虽阻带性能优良却存在带宽较窄的缺点 ,对E面金属双膜片结构进行了分析。提出了一种在保持金属双膜片结构优良性能的基础上实现较宽带宽的E面结构。据此设计了一个阻带性能优良的Ka波段波导滤波器。
Normal E plane double metal strip waveguide filters have high stopband performance, but the band is narrow. After analyzing this structure a method to get wider band and keep the high performance for this structure is presented in this paper. A Ka band E plane waveguide filter is designed.The numerical results agree well with the experimental data.
