摘要: 本文采用模式展開(kāi)方法,導(dǎo)出了波導(dǎo)E面金屬片濾波器的散射參量,進(jìn)而編寫(xiě)了濾波器優(yōu)化設(shè)計(jì)程序,設(shè)計(jì)、制造和測(cè)試了一個(gè)長(zhǎng)三厘米濾波器,實(shí)驗(yàn)結(jié)果和理論結(jié)果符合得很好。本文方法考慮了高次模式通過(guò)諧振腔發(fā)生的耦合,設(shè)計(jì)的濾波器特性比較理想,在頻率的低端和高端阻帶衰減都較大,所以比采用變分原理導(dǎo)出等效網(wǎng)絡(luò)參數(shù)然后進(jìn)行綜合設(shè)計(jì)的方法優(yōu)越。

Abstract: An optimization design theory and algorithm have been developed for waveguide E-plane metal insert filters. The immediate higher order mode coupling in resonator between the discontinuities, which reduces the stop band attenuation for higher frequencies is taken into account. An optimized design filter has been fabricated and tested in low X-band. Good agreement with design has been obtained. -
