Tuning the Resonance Frequency and Miniaturization of a Novel Microstrip Bandpass Filter
In this paper, a compact microstrip bandpass filter is designed using two open loop resonators. In order to obtain a tunable bandpass response with low insertion loss, two stubs are loaded inside them. The design process is based on obtaining the input admittance. Then, using the input admittance, a method is presented …
