Coupled-line filter with folded corners

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Two coupled lines with different spacing can be combined as a new configuration with folded corners. In a twostage half wavelength resonators filter, the couplings using this configuration can be controlled to provide the required coupling for the fundamental passband, and a transmission zero at the second spurious harmonic frequency. This configuration is then further extended as a four-stage cross-coupled resonator filter.
