The electronic device may receive and transmit signals through the antenna, and certainly, the electronic device may set the number of the antennas according to communication needs. For example, the first antenna may operate on a 5G signal based on the 5G-NR standard, and may be capable of transmitting or receiving signals at 1.8GHz and 2.4-2.5 GHz.
A communication system corresponding to at least two different frequency bands. The communication system may use signals to enable the electronic device to communicate with external devices, such as to receive and process signals sent by or to transmit signals to external devices. In one embodiment, the communication system has at least two communication subsystems, each communication subsystem corresponds to a corresponding frequency band signal, and each communication subsystem can receive or transmit a signal in a corresponding frequency band and process the received signal.
An auxiliary circuit disposed between the first antenna and the communication system, the auxiliary circuit including at least two paths, the at least two paths corresponding to at least two different frequency bands; the at least two paths simultaneously acquire signals of the first antenna, and the signals flow through the at least two paths, so that at least one path outputs signals of a frequency band corresponding to the at least one path. Specifically, one channel may correspond to one frequency band to transmit or receive signals of the frequency band, and two or more paths can simultaneously acquire the signals transmitted by the first antenna, so as to reduce signal loss of the electronic device. The circulation of signals through at least two paths allows at least one path to output signals of its respective frequency band to the communication system, for example, only one path outputs signals of its respective frequency band (single frequency band signals), or different paths output signals of their respective frequency bands (multiple signals of their respective frequency bands), for reception by the communication system.

The first channel is provided with a first matching module, a first suppression module and a second matching module, wherein the second matching module can match the signal of the first frequency band to a communication subsystem (such as a first communication subsystem) corresponding to the first channel by utilizing the characteristics of an electric element of the second matching module, and the first matching module can assist the second matching module to complete the matching task of the signal of the first frequency band, so that the matching accuracy of the signal of the first frequency band is improved. The first suppression module is used for suppressing signals except for a first frequency band in at least two frequency bands, such as signals of a second frequency band except for the signals of the first frequency band, signals of a third frequency band and the like. So that only the signals of the first frequency band can be output by the first path after the signals transmitted from the antenna pass through the first path.
Similarly, the second path is provided with a fourth matching module, a second suppression module and a third matching module, wherein the third matching module can match the signal of the second frequency band to the communication subsystem (such as the second communication subsystem) corresponding to the second path by using the characteristics of the electric element of the third matching module, and the fourth matching module can assist the third matching module to complete the task of matching the signal of the second frequency band, thereby improving the accuracy of matching the signal of the second frequency band. The second suppression module is used for suppressing signals except for the second frequency band in at least two frequency bands, such as signals of the first frequency band except for signals of the second frequency band, signals of the third frequency band and the like. So that only the signal of the second frequency band can be output by the second path after the signal transmitted from the antenna passes through the second path.
In an embodiment of the present application, as shown in fig. 2, the first matching module and the fourth matching module are the same matching module, and the second path is a first matching module of the first path.

Therefore, the frequency division effect is achieved under the condition that a special frequency divider is not used, the communication system can simultaneously acquire the signal of the first frequency band and the signal of the second frequency band, and the communication efficiency is improved.
On the other hand, the first path and the second path simultaneously receive the signal of the first frequency band of the single frequency band, so that the first path can output the signal of the first frequency band, and the second path does not output the signal because the signal of the first frequency band is suppressed, that is, the second path does not output any signal. The electronic equipment can be enabled to communicate even if the first antenna only uses signals of the first frequency band of the single frequency band, such as signals of only 1.8 GHz.
In another aspect, the first path and the second path simultaneously receive the signal of the second frequency band, which is a single frequency band, from the antenna, so that the second path can output the signal of the second frequency band, and the first path does not output the signal because the signal of the second frequency band is suppressed, i.e., the first path does not output any signal.
