Abstract:
A center electrode assembly comprising:a ferrite member having a top surface, a bottom surface and side surfaces connecting the top surface and the bottom surface; a ground plate provided at the bottom surface of the ferrite member; and a plurality of central conductors; wherein each of the central conductors includes a grounded leg portion which extends upward from the ground plate and along one of the side surfaces of the ferrite member, and which grounded leg portion is bent at an upper ridge portion of the ferrite member and extends on the top surface of the ferrite member, and wherein the grounded leg portion of each of the central conductors is bent in a such manner that the grounded leg portion is substantially perpendicular to the upper ridge portion of the ferrite member, and angular points of the central conductors, the angular points determining the crossing angle of the central conductors, are positioned on the top surface of the ferrite member.
