ABSTRACT:
An antenna frame that can suppress shock given to an antenna and position the antenna with controlling increase in size to a minimum, an antenna structure, and a wave clock having the antenna structure are provided. An antenna frame of an antenna structure of a wave clock comprises a frame made of a nonconductive material for receiving and fixing an antenna having an elongated and rod-like, magnetic core and a winding wire wound on the center in a longitudinal direction of the magnetic core. The frame has a recess including a recess portion for receiving a winding portion of the antenna and recess portions for receiving two ends of the magnetic core at both sides of the portion, and end mountings to be mounted on a base at the two ends. When the antenna is received in the recess, ends of the magnetic core are positioned with respect to the portions. The end mountings are mounted on the base in a manner of being contacted to a mounting surface at base side surfaces.
