Abstract:
1. A circuit array, comprising: a substrate; an electrically conducting folded dipole antenna arranged on and/or in the substrate, the folded dipole antenna having a first antenna connection and having a second antenna connection; wherein the folded dipole antenna has a disconnected portion dividing the folded dipole antenna in a first antenna portion and in a second antenna portion such that a capacity is formed at the disconnected portion between the first antenna portion and the second antenna portion; an integrated circuit arranged on and/or in the substrate and connected to the folded dipole antenna; wherein the material and/or the dimensions of the folded dipole antenna is/are configured such that the value of the impedance of the folded dipole antenna essentially equals the complex conjugate of the impedance of the integrated circuit; and at least one electronic member at the disconnected portion adapted such that the at least one electronic member regulates the impedance of the folded dipole antenna such that the value of the impedance of the folded dipole antenna is adapted to a change in an environmental condition so that the value of the impedance of the folded dipole antenna essentially equals the complex conjugate of the impedance of the integrated circuit.
