Abstract

The embodiment of the application provides a PCB used in a wireless terminal and the wireless terminal. According to the embodiment of the application, the PCB comprises a resonant part which generates a resonant current, and the current distribution of the PCB can be changed, thereby enabling the isolation between at least antennas to be increased. In addition, the resonant current can improve the capability of electromagnetic radiation of the PCB, thereby enabling the radiation efficiency of each antenna to be increased, improving the wireless performance of the wireless terminal, effectively guaranteeing the wireless performance of the wireless terminal in various application scenes. Moreover, the wireless terminal provided by the embodiment of the application is simple, is easy to achieve, and is low in cost.

Description

technical field [0001] The present application relates to communication technologies, and in particular to a printed circuit board (Printed Circuit Board, PCB for short) applied to a wireless terminal and a wireless terminal. Background technique [0002] With the rapid development of wireless communication technology, multi-antenna technology has been increasingly applied to various wireless terminals, for example, Long Term Evolution (LTE for short) system or Worldwide Interoperability for Microwave Access (Worldwide Interoperability for Microwave Access, hereinafter referred to as WIMAX) in the user equipment (User Equipment, UE). The multi-antenna technology refers to the use of multiple antennas at both the transmitting end and the receiving end to transmit or receive signals, that is, a multi-antenna system using the multi-antenna technology includes multiple transmission channels and multiple reception channels. [0003] However, since the distance between the multip...
