ABSTRACT:
A wrist band antenna prevents connection failure and/or breakdown due to attachment/detachment of a loop antenna and has a receivable frequency band which is not affected by the thickness of the wearer's arm. A U-shaped antenna structure is mounted inside a wrist band part which is part of the wrist band divided at the center fastening structure. The U-shaped structure functions as an independent antenna on at least one part of the wrist band. The antenna is buried in the wrist band part so that the two ends of its U-shaped structure face toward a receiver main body. When each of two contact pins on the ends of the U-shaped structure connect the wrist band with the receiver main body, a terminal spring on a reception circuit substrate of the receiver main body is pressed. This causes the receiving signal from the antenna to be conveyed to the receiver main body.
