Abstract
A microwave filter having a filtering effect against specific frequencies is fabricated by erecting a second dielectric substrate on the upper surface of a first dielectric substrate, a resonating circuit is formed by locating strip lines facing towards each other on both surfaces of this second dielectric substrate, and the strip lines are connected to input and output lines on the first dielectric substrate.
