<P>PROBLEM TO BE SOLVED: To provide a highly strong and solid dielectric line filter which is easily worked and is suitable for mass production. <P>SOLUTION: The dielectric constant of part of a dielectric strip 4 is adjusted so that transmission of a signal in a prescribed frequency band is interrupted in a dielectric line filter X in which a dielectric medium 3 and the dielectric strip 4 are arranged between two conductor boards 1 and 2 which are almost parallel and a dielectric line is used for transmitting the signal through the dielectric strip 4. The dielectric medium 3 and the dielectric strip 4 are constituted of porous materials which are substantially identical. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
