Abstract :
A novel compact and simple microstrip patch bandpass filter structure using only one resonator is presented. This filter has two transmission zeros on both sides of the passband. Without coupling gaps, the new filter can reduce uncertainty in fabrication. Simulated results agree well with measured results.
