Zusammenfassung:	A method and device for static tuning of wireless transmitters is disclosed. In some aspects, the antenna circuit can be located on a circuit board and configured to generate a wireless field and resonate at a resonant frequency. A tuning signal is applied an antenna circuit to drive the antenna circuit. A signal of the resonant frequency of the antenna circuit is detected and an adjustment value is determined based on the detected signal. A reactance of a variable reactance component is adjusted based on the adjustment value to maintain the resonant frequency in a range between a first frequency that is less than the detected resonant frequency and a second frequency that is greater than the detected resonant frequency.
