The present invention relates to an antenna matching structure, an antenna matching method and a wireless communication terminal. In which, the antenna matching structure comprising: a measuring unit configured to measure a RSSI value; a control unit configured to generate a first switching control signal when the RSSI value measured by the measuring unit is less than a predetermined threshold; and a parameter switching unit configured to select one set of matching parameters from predetermined at least one set of matching parameters according to the first switching control signal, and switch current matching parameters of the adjustable antenna matching circuit to the selected matching parameters. According to the embodiments of the present invention, a higher RSSI value can be acquired to ensure the signal transmission quality.
