Embodiment 1

[0034] In this embodiment, an intelligent mobile terminal with WiFi, BT and GPS functions is specifically described by taking a TD-SCDMA / GSM dual-mode mobile phone as an example. Since the working frequency range of WiFi and BT is 2400-2483.5MHz, the center frequency of GPS working is 1575.42MHz. Both operating frequencies are relatively high, but the frequency interval between them is relatively large, above 800MHz. Therefore, the respective air interface communication can be completed through the two antenna radiation units, and then the WiFi, BT signal and GPS signal can be separated into their respective signal channels through the corresponding band-pass filter. Then complete the data communication function through a series of data processing units.

[0035] Such as figure 2As shown, the multi-mode mobile terminal and its communication method provided by Embodiment 1 of the present invention include an antenna unit, a signal gating unit 1, a signal gating unit 2, a WiF...

Embodiment 2

[0043] image 3 The functional structural diagram of the multi-mode mobile terminal provided by the present invention, the difference between this embodiment and embodiment 1 is that the signal gating unit 2 of this embodiment adopts a signal separation mode from the WiFi and BT functional units, and the signal gating unit 2 has four radio frequency ports, one end is a common end, which is connected to the signal gating unit 1, and is a common path for WiFi, BT and GPS radio frequency signals, and the other three ports are separated WiFi and BT signals respectively. One of them is the WiFi transmission signal path, which only allows the WiFi transmission signals from the WiFi and BT functional units to pass through; the second path is the WiFi and BT reception signal path, which only allows the WiFi and BT reception signals from the signal gating unit 1 to pass through; The third path is the BT transmission signal path, which only allows BT transmission signals from WiFi and B...

Embodiment 3

[0045] This embodiment provides a method for multiplexing antennas in a multi-mode mobile terminal, the method is applied to the multi-mode mobile terminal provided by the present invention, and each step flow corresponds to the module function in the multi-mode mobile terminal provided by the present invention, The method includes:

[0046] Step 1, WiFi, BT and GPS signals share one antenna unit, and the antenna unit completes the reception and transmission of WiFi, BT and GPS signals respectively;

[0047] A first radiation unit and a second radiation unit are set in the antenna unit, and through the first radiation unit, WiFi and BT signals are received and transmitted, and corresponding air interface communication functions are completed; GPS air interface signals are received through the second radiation unit; the second radiation unit One radiating unit and the second radiating unit share a feed point and communicate with the signal gating unit 1 to complete the transmis...

Abstract

The invention discloses an antenna multiplexing method and a multimode mobile terminal. The antenna multiplexing method and the multimode mobile terminal are used for solving the technical problems of reduction in antenna performance and design complexity of the conventional mobile terminal, which are caused by the increase of an antenna number of a mobile phone. A first radiation unit and a second radiation unit are arranged in an antenna unit. Wireless fidelity (WiFi) and Bluetooth (BT) signals are received and transmitted through the first radiation unit, and global positioning system (GPS) air interface signals are received through the second radiation unit to respectively finish corresponding air interface communication functions. The WiFi, BT and GPS signals are separated through corresponding band-pass filters, and enter own signal channels, and a data communication function is finished through a series of data processing units. WiFi, BT and GPS antennae can be multiplexed to ensure the performance of each function module antenna of the mobile terminal, the antenna number of the multimode intelligent mobile terminal can be maximally reduced to save cost to a certain extent, and a subsequent intelligent design method for the multimode mobile terminal also can be guided to a certain extent.

Description

technical field [0001] The present invention relates to the field of communication, in particular to a multimode mobile terminal antenna multiplexing method and a multimode mobile terminal using the method. Background technique [0002] With the advent of the 3G era, mobile communications have fully entered the 3G era. At present, there are three major 3G communication standards in the world, namely Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (Code Division Multiple Access 2000, CDMA2000) and Time Division Synchronous Code Division Multiple Access (Time Division- Synchronous Code Division Multiple Access, TD-SCDMA) three systems. Among them, TD-SCDMA is an international standard proposed by my country and adopted by the International Telecommunication Standardization Organization. my country has core independent intellectual property rights. At present, China Mobile's TD-SCDMA network has accumulatively obtained 85MHz frequencies, whi...
