る盗難防止用タグ。 A receiving antenna section that receives high frequency power emitted from the outside, a multiplier diode that multiplies the high frequency power received by the receiving antenna section to an integral multiple of the frequency, and a multiplier diode that radiates the multiplied high frequency power to the outside. An anti-theft tag used in an anti-theft system in which a transmitting antenna part is formed on an insulating member of a predetermined shape, and the receiving antenna part excludes one short edge of the rectangular insulating member. A conductive layer with a predetermined width is formed in a U-shape on the side edge, and a rectangular closed conductive layer with a predetermined radius is formed at a predetermined position within the receiving antenna section as a transmitting antenna section. In order to electrically couple with the antenna part, one long side edge piece of the receiving antenna part and one piece of the transmitting antenna part facing the long side edge piece are connected with a conductive pattern of a predetermined width. At the same time, the multiplier diode is connected to the right angle part between the other long side edge piece and the short side edge piece of the receiving antenna part, and to the right angle part on the transmitting antenna part corresponding to the right angle part. In the anti-theft sheet connected between the receiving antenna part and the transmitting antenna part, conductive layers of a predetermined width are mutually connected from the right angle part of the receiving antenna part and the transmitting antenna part.
A pair of extension parts are formed at the tip of the conductive layer so as to protrude so as to face each other with a predetermined gap in between, and extend a predetermined length in the direction in which the anti-theft tag is wound up when manufacturing the anti-theft tag. An anti-theft tag characterized in that the multiplier diode is connected between the extensions of the layers.
