Design Of Multimode Bandpass Filter With Microstrip Resonator Loaded Capacitors Using Optimization Techniques
This paper introduces a new way to reduce the length of a microstrip end-coupled resonator by loading its ends by a lumped capacitors. A new way of controlling the frequency of the 2nd harmonic even mode by loading the center of the resonator by a lumped capacitor directly or through less than 0.125 λgo part of a microstrip transmission line. ... إقراء المزيد
