Claims

[Scope of utility model registration request]

A dielectric substrate, a ground conductor plate placed on the lower surface of the dielectric substrate, a main conductor line formed on the dielectric substrate, and one end shorted and the other end placed parallel to the side surface of the main conductor line. A microstrip band-stop filter comprising an open coupled conductor line and a metal shield plate that surrounds the dielectric substrate, the main conductor line and the coupled conductor line to shield them from electromagnetic radiation,
A microstrip band rejection filter characterized in that a coupled conductor line having one end closed and the other end open, similar to the coupled conductor line, is provided on the side surface of the main conductor line opposite to the coupled conductor line.
