  • Patent number: 6597263
    Abstract: A dielectric filter having a notch pattern includes a dielectric block, in which a ground face plated with conductive metal for all the rest portions excepting an upper face thereof and both side given portions of one side wall face connected to the upper face is formed and numerous patterns plated with the conductive metal are formed on the upper face as a non-conductive part, input electrode provided on one portion out of non-conductive portions and formed so that a signal from the outside may be inputted thereto, at least two resonators formed piercing through upper and lower faces of the dielectric block, a lower end part of which is short-circuited on a lower face as the ground face of the dielectric block, wherein two resonators are connected with each other through a pattern formed on the upper face of the dielectric block in order to resonate and wave-transfer a signal inputted through the input electrode, and output electrode provided in the rest one portion out of the non-conductive portions on one
