Description

technical field

[0001] The invention relates to the technical field of communication, in particular to an electronic device. Background technique

[0002] With the rapid development of mobile communication technology, people continue to put forward higher requirements for the capacity and transmission rate of the communication system. A series of network capacity improvement technologies and architectures have been proposed, and the antenna is an important part of the mobile communication system. The base station The downlink signal from the base station to the user equipment can be sent to the user equipment through an antenna (antenna), and the uplink signal sent to the user equipment can be received.

[0003] Antenna is a kind of converter, which converts the guided wave propagating on the transmission line into electromagnetic wave propagating in the unbounded medium, or performs the opposite transformation, that is, converts the electromagnetic wave into a guided wave. ...

Examples

Embodiment 1

[0092] Embodiment 1 of the present invention introduces an electronic device according to an embodiment of the present invention by taking the electronic device as a mobile phone, the first antenna 12 as a first FPC antenna, and the second antenna 13 as a second FPC antenna as an example.
