Abstract :
A microwave square ring resonator is a very narrow band bandpass filter (BPF) being widely used in telecommunication systems. Its spurious harmonics deteriorate its stopband performances. Two embedded open stubs are added to the feeding lines of a square ring resonator to suppress its first harmonics. Design details are proposed and simulations show that the first harmonics is suppressed by more than 30 dB.
