Cl circuit element and series resonance type band stop filter

Abstract

Abstract PURPOSE: To obtain a CL circuit element used as a miniaturized antenna shared device by forming first and second peeled zones, which do not intersect each other, around an outer conductor and using the outer conductor between peeled zones as a conductive feeding part. CONSTITUTION: A dielectric 4 having a uniform dielectric constant is packed among a cylindrical inner conductor 1, an outer conductor 3, and a conductive feeding part 10 to obtain a coaxial line 12. In one of both cut ends of the coaxial line 12, the inner conductor 1 is short-circuited to the lower outer conductor 3 by a bottom part conductor 6 and an upper part conductor 7 is opened as the first peeled zone 5 1 . The second peeled zone 5 2 peeled with a certain width into a zone is formed around the part between the outer conductor 3 and the conductive feeding part 10. In this constitution, the conductive feeding part 10 and the inner conductor 1 form a capacitance C 1 and the inner conductor 1 forms an inductance L 1 to obtain the series CL circuit element.
