LOW PASS FILTER USING CORRUGATED WAVEGUIDE AND METHOD FOR PRODUCING LOW PASS FILTER USING THE SAME

摘要

Disclosed is technology about a low pass filter for a satellite communication using a corrugated waveguide. The low pass filter using the corrugated waveguide includes the waveguide which includes a rectangular parallelepiped shape with a through hole in a longitudinal direction, the corrugated waveguide which is composed of at least one first T-junction and is combined with the lower end of the waveguide, and an impedance transformer which is composed of at least one second T-junction and is combined with both ends of the corrugated waveguide. Therefore, provided is the low pass filter for the satellite communication with high reflection loss and isolation properties and a low insertion loss property.
