Abstract (en)

[origin: US2007194865A1] An improved high frequency filter of coaxial construction comprises one or more resonators having an electrically conductive internal conductor configured as an internal conductive tube and an electrically conductive external conductor. An electrically conductive base electrically interconnects the internal conductor and the external conductor. A cover covers the high frequency filter with respect to the base; and an inner side and outer side. The inner sided points toward a free end of the internal conductive tube. A dielectric layer having a dielectric constant E<SUB>r </SUB>greater than 2 is arranged between the outer side of the covers and the free ends of the internal conductive tube. The radial extent of the dielectric layers substantially covers the cross section of the internal conductive tubes at the free ends thereof.
