Antenna for receiving-transmitting unit for detection of transponders e.g. for anti-theft prevention, has antenna conductor arrangement on/in carrier element

摘要

An antenna (20) for a receiving-transmitting unit has an antenna conductor (22) arranged on and/or in a carrier element (21), in which the carrier element (21) forms with the antenna line a flexible unit, and in which the antenna conductor (22) in the flat state of the unit, unavoidably covers a remaining defined surface (25) or spreads over such a surface. Independent claims are given for the following: (A) An arrangement of several antennae. (B) A transponder detection device. (C) Persons- or animal-detection device. (D) Object-detection device with transponder detection device.
