Abstract
The present invention discloses an antenna impedance matching method which is used for adjusting an impedance of an antenna to match an impedance of a radio frequency (RF) integrated circuit (IC). The method comprises the following steps of: (1) providing an antenna matching IC; (2) obtaining a used frequency band of the RF IC, so as to obtain a frequency band signal; (3) adjusting an impedance of the matching IC according to the band signal, so that the antenna achieves impedance matching. In summary, the present invention uses the matching IC to instead of a traditional matching circuit, and according to the band signal of the RF IC to adjust and match the impedance of the IC, so as to change the resonance and impedance of the antenna, and to achieve the impedance matching.
