Abstract :
A seven-pole high temperature superconducting (HTS) microstrip bandstop filter at L band is presented in this paper. The filter has application in a radio astronomy receiver. The zig-zag loop resonator and the zig-zag phase line are developed to reduce the parasitic effect of the direct resonator-to-resonator coupling. The measured results match the simulated results very well.
