Abstract:

This paper presents an inline terahertz THz waveguide bandpass filter BPF based on the bandstop resonator pairs It is implemented by E plane stubs The proposed resonators operate at the lower and upper stopbands of the designed BPF to provide sharp roll off and out of band rejection Both stopbands can be controlled independently and cascaded in parallel from source to load without mutual interference The unloaded quality factors of E plane stub resonators determine the bandwidths of both stopbands which are equal to the spurious free frequency ranges of the lower and upper stopbands respectively Since the proposed BPF design adopts bandstop resonator pairs resonating at the rejection band it will achieve a lower transmission loss than the conventional BPFs with resonators at the passband A 5th order BPF with a minimum measured insertion loss of 0 2 dB and 11 1 dB bandwidth at 250 GHz is fabricated The measurement results verify that multiple transmission zeroes TZs are achieved at the lower and upper stop bands respectively
