Abstract

PURPOSE:To form an antenna with the capacity using a human body as a dielectric substance and the loop inductance, by attaching an antenna member along the lengthwise direction of a belt and at the same time attaching a terminal which is connected to the antenna member to the belt. CONSTITUTION:A buckle 2 made of a conductive metal is attached at an end part of a belt 1, and plural pins 3 of conductive metals are provided at the other end of the belt 1. The buckle 2 engages with one of these pins 3. At the same time, an antenna member 4 made of a flexible material is buried along the lengthwise direction of the belt 1. An end of the member 4 is electrically connected to the buckle 2, and the other end is electrically connected to the pin 3. A connector device 6 is set at a proper area of the belt 1. A jack 7 is provided to the device 6, and at the same time the terminals 8 and 9 which are connected to the member 4, a balun 10, etc. are incorporated into the device 6.
