the first main board 10 is disposed opposite to the second main board 20 and connected with the flexible board 40;
the first main board 10 is provided with a first rf area 11 for approaching the main antenna 50, a main antenna feeding point 111 is disposed in the first rf area 11, and the rf main module 31 is fixed in the first rf area 11 and is electrically connected to the main antenna feeding point 111.
In the prior art, the radio frequency main set module 31 is generally disposed on a motherboard at the top of the mobile terminal 300, and the main set antenna 50 is disposed on a motherboard at the bottom of the mobile terminal 300 (i.e. the first motherboard 10), and the radio frequency main set module 31 and the main set antenna 50 are connected through a long cable, so that the transmission efficiency between the radio frequency main set module 31 and the main set antenna 50 is reduced, and the Over The Air (OTA) performance of the mobile terminal 300 is reduced, especially when the mobile terminal 300 is in a weak signal environment, which seriously affects the network experience of the user.
In the embodiment of the present invention, the first main board 10 is provided with the first rf area 11 close to the main set antenna 50, and the first rf area 11 is internally provided with the feeding point 111 of the main set antenna 50, the main set rf module 31 is fixed in the first rf area 11, and the main set rf module 31 and the feeding point 111 of the main set antenna 50 are electrically connected in the first rf area 11, so that the cable length between the main set rf module 31 and the feeding point 111 of the main set antenna 50 is shortened, or the cable is omitted, that is, the attenuation of the rf signal is reduced, and the antenna performance is improved. On the other hand, since the first motherboard 10 is disposed opposite to the second motherboard 20 and connected by the flexible board 40, the flexible board 40 is only used for routing, and no components are required to be mounted on the flexible board 40, so that the length of the flexible board 40 can be saved, and the number of the flexible boards 40 can be reduced. The flexible board, also called flexible circuit board (Flexible Printed Circuit abbreviated as FPC).
In the embodiment of the present invention, each of the first motherboard 10 and the second motherboard 20 is composed of a substrate and a circuit disposed on the substrate. The first rf area 11 is an area where electronic components are arranged on one surface of the first motherboard 1. The boundary of the first rf region 11 may enclose the rf main set module 31 and the main set antenna feeding point 111. When the first motherboard 10 is fixed to the mobile terminal 300, the first rf region 11 is close to the main set antenna 50 of the mobile terminal 300. It is understood that the first main board 10 may further include other areas outside the first rf region 11, and that the first area 11 is close to the main set antenna 50 means that the distance from the first area 11 to the main set antenna 50 is smaller than the distance from the other areas of the first main board 10 to the main set antenna 50. The distance from the first rf region 11 to the main set antenna 50 is reduced, and the cable length between the first rf region 11 and the main set antenna 50 is reduced or the cable from the first rf region 11 to the main set antenna 50 is omitted. The main rf collector module 31 may be electrically connected to the main collector antenna feed point 111 through a metal spring. The main set antenna feed point 111 may be electrically connected to the main set antenna radiator of the main set antenna 50 through a metal elastic sheet, so that when the radio frequency main set module 31 transmits the main set radio frequency signal to the main set antenna radiator through the radio frequency transmission module, a cable for transmitting the main set radio frequency signal between the main set antenna feed point 111 and the main set antenna 50 is omitted, attenuation of the main set radio frequency signal is reduced, and antenna performance is improved. Alternatively, the main set antenna feed point 111 may be located at an edge of the first rf region 11 near the main set antenna 50.

The main rf set module 31 is responsible for feeding rf signals to the main set antenna 50, and the main rf set module 31 is a rf power supply of the main set antenna 50. The electronic components of the main rf collection module 31 are arranged in the first rf area 11 in a scattered manner, so that the usage area of the first rf area 11 is fully utilized, the area of the first rf area 11 is minimized, and the volume of the circuit board 10 is fully optimized. Since the rf main set module 31 and the main set antenna feeding point 111 are both located in the first rf region 11, the distance between the rf main set module 31 and the main set antenna feeding point 111 is reduced. The rf main set module 31 and the main set antenna feeding point 111 may be directly electrically connected (e.g. electrically connected through a spring plate), or may be electrically connected through a shorter cable, i.e. the length of the cable connecting the rf main set module 31 and the main set antenna feeding point 111 may be reduced, or the cable connecting the rf main set module 31 and the main set antenna feeding point 111 may be omitted.
In one embodiment, the radio frequency module further includes a radio frequency diversity module 32, and a diversity antenna feeding point 112 is further disposed in the first radio frequency area 11, and the radio frequency diversity module 32 is fixed to the first radio frequency area 11 and is electrically connected to the diversity antenna feeding point 112.
In the implementation of the invention, the radio frequency diversity module 32 and the radio frequency main set module 31 are both arranged on the main board (namely the first main board 10) at the bottom of the mobile terminal 300, and as the radio frequency diversity module 32 and the diversity antenna feed point 112 are both arranged in the first radio frequency region 11, cables are omitted between the radio frequency diversity module 32 and the diversity antenna feed point 112, namely, the attenuation of radio frequency signals is reduced, and the antenna performance is improved.

The rf diversity module 32 may be electrically connected to the diversity antenna feed point 112 through a metal dome. The diversity antenna feed point 112 may be electrically connected to the diversity antenna radiator of the diversity antenna 60 through the metal spring, so that when the rf diversity module 32 transmits the diversity rf signal to the diversity antenna radiator through the rf transmission module, a cable for transmitting the diversity rf signal is omitted between the diversity antenna feed point 112 and the diversity antenna 60, thereby reducing attenuation of the diversity rf signal and improving antenna performance.

The rf transceiver chip 33 may be located in the first rf region 11 closer to the rf main set module 31 and the rf diversity module 32. The boundary of the first rf region 11 may also enclose the rf transceiver chip 33. The length of the cable between the rf transceiver chip 33 and the rf main set module 31 is reduced, or the cable between the rf transceiver chip 33 and the rf main set module 31 is removed, so that the attenuation degree of the rf signals transmitted and received by the rf transceiver chip 33 is reduced, and the antenna performance is improved. The length of the cable between the rf transceiver chip 33 and the rf diversity module 32 is reduced, or the cable between the rf transceiver chip 33 and the rf diversity module 32 is removed, so that the attenuation degree of the rf signal transmitted and received by the rf transceiver chip 33 is reduced, and the antenna performance is improved.

The GPS radio frequency module 70 is electrically connected to the network antenna feed point 113 by a cable.
The second radio frequency area 21 may be located the second mainboard 20 is close to wifi antenna radiator department, makes the distance between wifi radio frequency module 80 and the wifi antenna radiator reduces, and then can remove the cable between wifi radio frequency module 80 and the wifi antenna radiator, perhaps reduces the cable length between wifi radio frequency module 80 and the wifi antenna radiator.
