Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035]Such as figure 1 As shown, PCB motherboard (PCB, Printed Circuit Board, Chinese name is printed circuit board, also known as printed circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical interconnection of electronic components. Because it is made using electronic printing, it is called a "printed" circuit board) includes 3 feeds (ie figure 1 3 feeds 1) in each feed 1 through an RF cable (ie figure 1 RF cable1) in the antenna board and antenna 1 ( figure 1 There are 3 antennas set on the small antenna board in the ...

Abstract

The invention discloses a signal transmission method and a mobile terminal. The mobile terminal comprises a PCB main board and a small antenna board. A plurality of antennas are arranged on the antenna small board, each antenna is provided with an independent antenna feed point on the antenna small board, and each antenna corresponds to a feed source on the PCB main board; the PCB main board is connected with the antenna small board through an RF cable, and the RF cable is used for transmitting an RF radio frequency signal from the PCB main board to the antenna small board; and or the RF cable is used for transmitting the signal on the antenna small board to the PCB main board. According to the invention, the mutual transmission of signals between the PCB main board and the antenna small board can be realized only by arranging one RF cable between the PCB main board and the antenna small board, the complexity of the structural design of the mobile terminal is reduced, the receiving and transmitting of each signal path are not influenced, and the degree of freedom of the structural design of the antenna is reserved to the greatest extent so as to achieve better antenna transceiving performance.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a signal transmission method and a mobile terminal. Background technique [0002] Mobile terminals or mobile communication terminals refer to computer equipment that can be used on the move, broadly speaking, it includes mobile phones, notebooks, tablet computers, POS machines and even vehicle-mounted computers. But in most cases, it refers to mobile phones or smart phones and tablet computers with various application functions. With the development of network and technology towards more and more broadband, the mobile communication industry will move towards the real mobile information age. On the other hand, with the rapid development of integrated circuit technology, the processing capability of the mobile terminal already has a powerful processing capability, and the mobile terminal is changing from a simple communication tool to a comprehensive information p...
