Wherein the plurality of metal segments 31 may form a plurality of antennas of the electronic device 100 for transmitting and/or receiving communication signals. Different metal segments 31 may form different antennas, or multiple metal segments 31 may form one antenna, or the same metal segment 31 may be multiplexed into multiple antennas. One antenna may cover one or more communication bands. Herein, "and/or" is only one kind of association relationship describing the association object, and means that there may be three kinds of relationships, for example, a and/or B, and may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two unless otherwise specified.

Understandably, the length, material, shape, and peripheral structure of the metal segment 31 determine the operating frequency band of the antenna, and the parameters of the metal segment 31 can be designed according to the requirement, which is not limited in the present application.

The Beidou short message function refers to a communication technology for directly carrying out bidirectional information transmission between the Beidou ground terminal and the Beidou satellite and between the Beidou ground monitoring master station through satellite signals. Therefore, the Beidou short message function is realized without the support of other communication systems, so that the Beidou ground terminal can realize the communication function in areas (such as unmanned areas, desert areas, polar areas and the like) which cannot be covered by communication signals or under the condition that a communication base station is damaged (such as earthquakes, floods, typhoons and the like). For example, the implementation of the beidou short message function requires the support of two antennas, and the two antennas are respectively used for transmitting and receiving beidou short message signals.

WiFi and bluetooth are wireless networking technologies that enable wireless communication within a certain range.

Cellular mobile communication is a wireless communication technology, and a mesh structure is adopted to realize large-area wireless communication. For example, cellular mobile communications may employ a variety of network types, such as: global system for mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Long Term Evolution (LTE), and the like. Cellular mobile communications may also employ multiple communications bands, such as: n41, N78, N79, and the like. In an embodiment of the present application, the electronic device 100 may employ N41 as an operating frequency band for cellular mobile communications.

Understandably, the electronic device 100 may also support other communication functions, such as: near Field Communication (NFC), Frequency Modulation (FM), Infrared (IR), and/or the like, which are not limited in this application.

The existing electronic device 100a, such as a mobile phone/PAD terminal, generally supports communication functions such as GPS L1, 2.4G WiFi, and cellular Band41, and the electronic device 100a includes modules, transceiving channels, and antennas corresponding to different communication functions. Specifically, the GPS L1 function corresponds to a GPS module, a GPS L1 path, and an L1 antenna; the 2.4G WiFi function corresponds to a WiFi module, a WiFi2.4G access and a 2.4G antenna; cellular Band41 functions correspond to RFIC (radio frequency integrated circuit), cellular N41 channels, and Band41 antennas. If the big dipper short message mode needs to be added, a radio frequency circuit transceiving channel and an independent antenna of big dipper need to be added separately, that is, an antenna needs to be added separately in the existing mobile phone/PAD terminal. The space of the existing mobile phone/PAD terminal is limited, and the increase of the number of antennas can influence the layout of the mobile phone and the performance of other antennas.

Referring to fig. 1 and4 together, fig. 4 is a schematic view of a part of the structure of the electronic device 100 shown in fig. 1.

Illustratively, the plurality of antennas may include a first antenna 311 and a second antenna 312, i.e., the bezel 3 may include the first antenna 311 and the second antenna 312.

The second module 72 is connected to the second antenna 312 via the second path 75, and can transmit and receive signals via the second antenna 312. The beidou baseband module 73 is connected with the first antenna 311 through the beidou uplink path 76 and is connected with the second antenna 312 through the beidou downlink path 77. The big dipper baseband module 73 transmits the big dipper short message signal through the first antenna 311, and receives the big dipper short message signal through the second antenna 312, thereby completing the big dipper short message communication.

For example, the working frequency band of the first antenna 311 may cover the working frequency band of the first module 71 and the working frequency band of the uplink mode of the beidou short message signal, so that the first antenna 311 may simultaneously implement signal transmission of the first module 71 and sending of the beidou short message signal. The working frequency band of the second antenna 312 may cover the working frequency band of the second module 72 and the working frequency band of the downlink mode of the beidou short message signal, so as to simultaneously implement the receiving of the beidou short message signal and the signal transmission of the second module 72.

For example, the first module 71, the second module 72, or the beidou baseband module 73 may include, but are not limited to, a radio frequency chip, a baseband chip, and related peripheral circuits.

For example, the beidou downlink 77 may include a second filter 773, a first Low Noise Amplifier (LNA) 772, and a third filter 771, which are connected in sequence. Wherein the second filter 773 is connected to the second switch 79 for filtering out the desired signal from the signal received by the second antenna 312. The first lna 772 is used to amplify the power of the signal at a given distortion rate. The third filter 771 is connected to the beidou baseband module 73 for further filtering the noise of the signal to obtain the required signal.

In this embodiment, the communication application signal sent by the beidou baseband module 73 is amplified by the first power amplifier 761 and removed by the first filter 762, and then is sent out through the first antenna 311, and then the outbound signal received by the second antenna 312 enters the beidou baseband module 73 after being screened by the second filter 773, expanded by the first low-noise amplifier 772 and removed by the third filter 771, and the beidou short message communication is completed by demodulating and decrypting the outbound message by the beidou baseband module 73.
