| 摘 要： | 介绍了一种新颖的波导类椭圆带阻滤波器.该滤波器的结构由传输TE10主模的矩形波导中的偏移半销钉和四分之一波长传输线组成.波导中半销钉的等效电路即在谐振频率处为一个串联LC谐振电路,此谐振电路产生一个衰减极点.销钉的高度主要用来控制谐振频率,销钉距离波导中心的偏移量用来控制谐振单元间的耦合强度.最后设计了一个中心频率为9...

| Abstract: | A novel inline waveguide pseudoelliptic band stop filter was introduced.Its partial structures were consisted of an offset partial-height post in a rectangular waveguide of the dominant TE10 mode and 1/4 wavelength transfer line.The equivalent circuit of the partial-height post is LC cascade resonant circuit at the resonant frequency and generated an attenuation pole.The resonant frequency was controlled by the post height.The offset value of the post from the center of the waveguide was used to control the... |
