Embodiment 1

[0054] This embodiment provides a method for NFC and FM to share a built-in antenna under the premise of ensuring that the functions of the mobile terminal remain unchanged, so as to implement multiplexing of the NFC antenna and the FM antenna on the mobile terminal product. Specifically, through the combined application of NFC and FM sharing built-in antenna, antenna switch control network, antenna matching network, FM protection network, FM low noise amplification network, NFC electromagnetic compatibility (Electro Magnetic Compatibility, referred to as EMC) filter network, not only The built-in FM antenna can be realized, and the performance of the built-in FM antenna can be improved. Moreover, compared with the external one, the FM built-in antenna has the same performance, better appearance characteristics, and is more robust.

[0055] Figure 4 It is a schematic diagram of a mobile terminal in which NFC and FM share a built-in antenna according to Embodiment 1 of the pr...

Embodiment 2

[0069] This embodiment provides a mobile terminal with NFC and FM functions and supports TD-SCDMA / GSM dual-mode communication. The composition of the mobile terminal is as follows figure 1 As shown, the NFC and FM multiplexing built-in antenna has two signal feed points, and the antenna switch control network composed of a single pole single throw switch, a single pole double throw switch and a control signal from the baseband chip completes the multiplexing of the NFC and FM antenna. At the same time, through the antenna matching network, FM protection network, low noise amplifier network, NFC EMC filter network, etc., the interference between multiple antennas can be reduced and the antenna performance can be improved.

[0070] Figure 5 is a schematic diagram of the built-in antenna used as an FM antenna according to Embodiment 2 of the present invention, as shown in Figure 5 As shown, when the user listens to FM radio, the baseband control chip controls the switch contro...

Abstract

The invention discloses a near field communication (NFC) dual-mode mobile terminal and a communication method thereof. The method comprises the following steps that: when a frequency modulation (FM) function of the mobile terminal is required to be used, the mobile terminal indicates a built-in antenna of the mobile terminal by a control network of the mobile terminal to receive a radio frequency signal from an FM transmitting station; and when an NFC function of the mobile terminal is required to be used, the mobile terminal indicates the built-in antenna by the control network to perform near field communication with a reader or a label in an electromagnetic induction way. In the NFC dual-mode mobile terminal and the communication method thereof, the number of antennae of the mobile terminal is reduced, system performance is enhanced, and user experiences are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a near field communication (Near Field Communication, NFC for short) dual-mode mobile terminal and a communication method thereof. Background technique [0002] With the arrival of the third generation mobile communication (The Third Generation Mobile Communications, 3G for short) era, the mobile communication has fully entered the 3G era. At present, there are three major 3G communication standards in the world, namely Wideband Code Division Multiple Access (WCDMA for short), Code Division Multiple Access (CDMA for short) 2000 and Time Division Synchronous Code Division Multiple Access (TCDMA). Access (Time Division-Synchronous Code Division Multiple Access, referred to as TD-SCDMA) three systems. Among them, TD-SCDMA is an international standard proposed by my country and recognized by the International Telecommunication Standardization Organization. my country has core indep...
