An fpc board with integrated antenna and switch key and mobile terminal

Abstract

The invention relates to the technical field of a mobile terminal and discloses an antenna and on-off key integrated FPC (flexible circuit board) and the mobile terminal. The FPC comprises a copper pouring region, an antenna energy feed point, an on-off key energy feed point, a grounding bonding pad and an on-off key spring sheet. The FPC of the on-off key is used; the antenna energy feed point and a main body are arranged on the FPC, wherein the antenna energy feed point, the copper pouring region and the grounding bonding pad are connected to form the main body of the antenna, equivalently, the FPC of the on-off key is transformed into the antenna; the on-off key energy feed point is also electrically connected with the on-off key spring sheet, so that the functions of the on-off key are maintained on the FPC; and the antenna and on-off key integrated FPC has the advantages that the antenna and the on-off key of power source share the FPC, so that a conventional BT / WIFI (British Telecom / Wireless Fidelity) antenna can be saved, the cost of the antenna is reduced, the antenna and on-off key integrated FPC is easy to realize and is suitable for mass production, and an ultra-thin mobile phone is prevented from limiting the antenna region to influence the normal working of the antenna.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an FPC board integrating an antenna and a switch key and a mobile terminal. Background technique [0002] The antenna is an indispensable part of wireless communication, and its basic function is to radiate and receive radio waves. When transmitting, the antenna converts high-frequency current into electromagnetic waves; when receiving, the antenna converts electromagnetic waves into high-frequency current. Antenna gain and radiation size are related to the size of the antenna. Existing mobile phones integrate BT (bluetooth, Bluetooth) and WIFI ((WirelessFidelity, wireless local area network based on IEEE802. [0003] However, with the rapid development of wireless communication technology, the performance requirements for mobile terminals in terms of intelligence, thinness, and ultra-long standby time are also getting higher and higher. As the mobile terminal becomes...
