A microwave square ring resonator is a narrow band bandpass filter (BPF) that can be widely used in microwave filters and oscillators. But its spurious harmonics generate harmful electromagnetic interferences, and must be removed. In this paper, two spurlines are tuned to suppress the first and the second harmonics of a square ring resonator. Simulations show both harmonics can be highly suppressed.
