The second signal source 3 now has a multi-frequency operating scenario. The compatibility of the same-frequency high-isolation and multi-feed-in multi-frequency antenna can be realized by switching the selector switch 4 between two working positions, so that the multi-antenna structure can be arranged in a narrow space.
It should be noted that the matching circuits (i.e. the first matching circuit 21, the second matching circuit 33, and the third matching circuit 34) are used to adjust the self-impedance of the antenna to be the same as the signal source, so that the maximum ratio of current energy can be converted into electromagnetic radiation energy through the antenna. The matching circuit may be a capacitor or an inductor, and those skilled in the art may select component matching and parameter values of the matching circuit according to different products and different design scenarios, which are not limited herein.
As shown in fig. 1, the radiator 1 may have an elongated structure, and the first feeding point 11, the second feeding point 12, and the third feeding point 13 are sequentially arranged along a same straight line direction of the radiator 1. The shape of the radiator 1 is not limited to the elongated shape, and may be any other shape.

In order to realize simultaneous operation of dual antennas with the same frequency, the distance from the first feeding point 11 to the first end 14 of the radiator 1 is equal to the distance from the third feeding point 13 to the second end 15 of the radiator 1. Therefore, as shown in fig. 2, when the switch 4 is switched to the first operating position, the first feeding point 11 to the first end 14 of the radiator 1 and the third feeding point 13 to the second end 15 of the radiator 1 can form antenna branches of the first frequency f1, respectively, and the two antennas with the same frequency have a higher isolation degree due to the grounding of the second feeding point 12, so that when the switch 4 is switched to the first operating position, the first signal source 2 and the second signal source 3 can implement simultaneous operation of the two antennas with the same frequency.
In order to implement a multi-frequency operation scenario, as shown in fig. 3, the switch 4 may be switched to the second operation position, such that the first signal source 2 forms an antenna branch of the first frequency f1 from the first feeding point 11 to the first end 14 of the radiator 1, the second signal source 3 forms an antenna branch of the second frequency f2 from the second feeding point 12 to the first end 14 of the radiator 1, and the second signal source 3 forms an antenna branch of the first frequency f1 from the third feeding point 13 to the second end 15 of the radiator 1. At this time, since the first signal source 2 and the second signal source 3 are both formed with an antenna branch of the first frequency f1, in order to prevent mutual interference, the first signal source 2 and the second signal source 3 can transmit signals in a time division multiplexing mode when transmitting the same frequency signal. The first signal source 2 and the second signal source 3 may transmit simultaneously when transmitting different frequency signals.
The embodiment of the present application does not limit the form of the radiator 1, and the radiator 1 may be a monopole antenna, a PIFA antenna, or an LOOP antenna, that is, a grounding point for changing the function of the antenna may be added to the radiator 1. These points of grounding that change the antenna function are not related to the effect of improving the antenna isolation.

According to the mobile communication device provided by the embodiment of the present invention, due to the multi-antenna structure described in any of the above embodiments, when the mobile communication device needs the first signal source 2 and the second signal source 3 to simultaneously operate in the scene of the same frequency dual antenna, the switch 4 can be switched to the first operating position, so that the switch 4 connects the second feeding point 12 of the radiator 1 to the ground, and disconnects the second feeding point 12 of the radiator 1 from the third matching circuit 34, thereby enabling the first feeding point 11 to one end of the radiator 1 and the third feeding point 13 to the other end of the radiator 1 to form antenna branches, and enabling the two antennas to have higher isolation due to the grounding of the second feeding point 12; when the mobile communication device needs the first signal source 2 and the second signal source 3 to implement dual-frequency operation, the change-over switch 4 may be switched to a second operating position, so that the change-over switch 4 connects the second feeding point 12 of the radiator 1 with the third matching circuit 34, and disconnects the second feeding point 12 of the radiator 1 from the ground, thereby enabling the first signal source 2 to have an antenna branch with a first frequency, and the second signal source 3 to have an antenna branch with two frequencies at two sides of the radiator 1 through the two feeding points, respectively. The second signal source 3 now has a multi-frequency operating scenario. The compatibility of the same-frequency high-isolation and multi-feed-in multi-frequency antenna can be realized by switching the selector switch 4 between two working positions, so that the multi-antenna structure can be arranged in a narrow space.
In order to save space, when the mobile communication device includes a metal case, the radiator 1 may be formed using the metal case, i.e., a portion is separately formed on the metal case to serve as the radiator 1 and is insulatedly connected with the remaining portion of the metal case. Thereby, material and installation space can be saved. And because the multiple antennas share one radiator 1, the metal shell does not need to be cut into a plurality of pieces, so that the process is simple and the structure is neat.
Specifically, as shown in fig. 4, the metal housing includes a metal rear shell 5 and a radiator 1, the metal rear shell 5 is in insulated connection with the radiator 1, the metal rear shell 5 is a reference ground, and a ground point of the radiator 1 is connected to the metal rear shell 5. Thereby, the reference ground is formed simultaneously with the radiator 1 by the metal case, so that the installation space and the material cost can be further saved.
As shown in fig. 4, the radiator 1 has a long structure and extends along the width direction of the mobile communication device, so that the radiator 1 can be designed to correspond to the width dimension of the metal rear case 5, and the back structure of the mobile communication device is more compact and neat.
In order to make the connection between the metal rear case 5 and the radiator 1 more stable, as shown in fig. 4, the first end 14 and the second end 15 of the radiator 1 may be formed as bent portions, and the metal rear case 5 may be formed with recessed portions at positions corresponding to the bent portions, so that the bent portions and the recessed portions are connected in a matching manner to improve the connection stability.
It should be noted that the mobile communication device in the embodiment of the present application may be a mobile phone, a tablet computer capable of talking, and the like, and is not limited herein.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention.
