Abstract :
A novel bandpass filter is presented using ring resonators employing corrugated couplers in order to provide suppression of the second harmonic. The filter exhibits a 2.0% bandwidth at a centre frequency of 2.604 GHz and provides a 39 dB suppression of the second harmonic. The constituent resonator is described and an analogous bandpass filter without corrugations is presented for comparison.
