Abstract

Область использовани  - частотно селективные устройства сверхвысоких частот. Цель изобретени  - уменьшение зависимости частотно-нормированной амплитудно- частотной характеристики от дизлектриче- ской проницаемости диэлекрической подложки полосно-прОпускающего фильтра. Полосно-пропускающий фильтр содержит диэлектрическую подложку 1 и микрополосковые полуволновые резонаторы 2. размещенные на ней и злектромагнит- но св занные один с другим. Длина в области электромагнитной св зи выбрана равной 0,646 длины каждого из микрополо- сковых полуволновых резонаторов 2. За счет этого сводитс  к нулк) емкостна  составл юща  св зи, а индуктивна  составл юща  менее чувствительна  к изменению диэлектрической проницаемости диэлектрической подложки 1. 1 ил.The field of use is frequency-selective devices of ultra-high frequencies. The aim of the invention is to reduce the dependence of the frequency-normalized amplitude-frequency characteristic on the dielectric constant of the dielectric substrate of the band-pass filter. The band pass filter contains a dielectric substrate 1 and microstrip half-wave resonators 2. placed on it and electromagnetically coupled to each other. The length in the electromagnetic field is chosen to be equal to 0.646 the length of each of the micro-strip half-wave resonators 2. Due to this, the capacitive coupling component is reduced to zero, and the inductive component is less sensitive to changes in the dielectric constant of the dielectric substrate 1. 1 Il.
