An antenna system, comprising a radiator, a first feeding end, a second feeding end, a grounding end, a first matching circuit, a second matching circuit and a third matching circuit, the first feeding end, the second feeding end The input end and the ground end are arranged at intervals, the radiator is arranged on the side of the first feed end, the second feed end and the ground end, and the first feed end is electrically connected to the radiator through the first matching circuit. connected, the second feeding end is electrically connected to the radiator through the second matching circuit, the grounding end is electrically connected to the radiator through the third matching circuit, and the first feeding end is used to receive the first feeding input signal, the antenna system works in the near-field communication mode under the action of the first input signal, and the second input terminal is used to receive the second input signal, and the antenna system operates in the second input signal It works in the far-field communication mode under the action. The antenna system can realize the sharing of far-field communication antennas and near-field communication antennas. The invention also provides a communication terminal.
Description
technical field [0001] The invention relates to the field of wireless communication, in particular to an antenna system and a communication terminal using the antenna system. Background technique [0002] Near Field Communication (NFC) technology is a short-range wireless communication technology that allows non-contact point-to-point data transmission and exchange data between electronic devices, and can be applied to mobile payment, electronic ticketing, access control and attendance and other fields. At present, NFC has gradually become an essential function of communication terminals such as mobile phones and tablet computers. The realization of the NFC function is inseparable from the antenna design. The existing NFC antenna requires a large space, and in order to avoid interference, it also needs to be equipped with an expensive ferrite that has the same area as the NFC antenna. The production cost of communication terminals such as computers. At the same time, with ...
