Problems solved by technology

[0004] However, the transmission power of a wireless communication device is related to the communication quality, reducing the transmission power of a wireless communication device is equivalent to reducing the communication quality of a wireless communication device
In other words, that is, while reducing the SAR, the method of the prior art also reduces the communication quality of the wireless communication device

Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] In the embodiment of the present invention, two antennas are connected to the common ground on the wireless communication device, and the electrical length of one of the two antennas is N times the electrical length of the other antenna, where N is an integer greater than or equal to 1, thereby reducing The input impedance of the ground poi...

Abstract

The invention discloses wireless communication equipment. A first antenna and a second antenna are arranged on the wireless communication equipment. The electrical length of the first antenna is N times of that of the second antenna, and N is an integer larger than or equal to one. The first antenna and the second antenna are arranged on a printing circuit board in a common ground connection mode, namely, the first antenna and the second antenna share the same grounding point, so that the input impedance of the grounding point of the first antenna and the grounding point of the second antenna is reduced, and energy fed through the antennas is made to be distributed in a relatively even mode in the horizontal direction and the perpendicular direction of the printing circuit board. Consequently, SAR is reduced on the condition that the communication quality of the wireless communication equipment is not reduced.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular, to a wireless communication device. Background technique [0002] With the development of information technology, while enjoying the convenience brought by information technology, the public is also concerned about the harm of electromagnetic radiation from wireless communication equipment to the human body. Among them, the electromagnetic wave absorption rate (Specific Absorption Rate, hereinafter referred to as: SAR) value is It is an important index to measure the harm of electromagnetic radiation to the human body. The higher the SAR value, the greater the harm to the human body. [0003] In order to reduce the harm of electromagnetic radiation to the human body, in the prior art, the SAR value is reduced by reducing the transmission power of the wireless communication device. [0004] However, the transmission power of the wireless communication device i...
