Abstract
The invention relates to an antenna construction for an RFID chip for long ranges, which comprises a substrate, an antenna of conducting material supported by the substrate, the antenna is formed as a magnetic dipole, and coupling means for coupling the antenna to a circuit, which coupling means are formed by overlapping extensions of the antenna conductor. In accordance with the invention the antenna is formed of at least three sections each of different width W1, W2 and W3, where the sections are widest and the section is the narrowest W2 with an optimized shape.
