Abstract
The emitter is intended to provide a contactless communication channel (particularly RFID/NFC) in miniature build space. The emitter has an oblong, at least partially ferrite core (), the core () is winded up by a wire () with at least two threads (), the threads () are on the core () placed tightly next to each other and the effective width (w)of one thread () corresponds to the radius of the core () in the circular core () cross-section, or corresponds to the equivalent radius in other shapes of the core () with deviation up to +−75%. The wire () of the coil is flat, or the coil includes several wires held parallel to each other (toN) forming a multi-stage thread. The emitter can be placed in the removable memory card () and/or on the PCB board () and/or SIM card () and/or battery (). Modulation of data transmitted by the emitter uses electromagnetic wave generator with a frequency different from the receiver, difference of these frequencies corresponds to the subcarrier frequency.
