Coil and device for wireless signal transmission, and method for producing such a coil

Abstract

The invention relates to a coil in the form of a transmitting and/or receiving coil of a device for wireless signal transmission by means of electromagnetic waves, wherein the coil has an impedance matching circuit for adapting the connection impedance of the coil to an input impedance of a signal transmitting and/or receiving device of the device for wireless signal transmission to be connected to the coil, wherein the impedance matching circuit is formed entirety or at least partially by at least partially overlapping conductor tracks of the coil. The invention also relates to a device for wireless signal transmission by means of electromagnetic waves, comprising a signal transmitting and/or receiving device and a coil connected to the signal transmitting and/or receiving device. The invention further relates to a method for producing such a coil.)
