Embodiment Construction
[0081] The communication function of the communication equipment is realized by the antenna set inside it, and the antenna will generate a certain amount of radiation when it works. It is not clear whether the radiation of the antenna will cause harm to the human body. There are corresponding standards, and communication devices with built-in antennas that meet this standard can only be used. Taking a mobile phone as an example, the antenna of the mobile phone needs to be less than a certain SAR value under the condition that it can normally cover the frequency band.
[0082] refer to figure 1 , is a schematic diagram of the antenna of the communication device of the related art, the antenna 1 is arranged above the circuit board 2, the antenna 1 includes a main antenna 11, and the lower end of the main antenna 11 is connected to the circuit board 2, which is the feeder 111. A first parasitic unit 12 and a second parasitic unit 13 are respectively provided on both sides, and t...

The antenna provided by the embodiment of the present application can be used for communication of a communication device.
Description
technical field [0001] The present application relates to the technical field of communication equipment, and in particular, to an antenna and communication equipment. Background technique [0002] At present, the communication function of communication equipment is realized by the antenna set inside it. With the miniaturization of communication electronic equipment, the convenience and functionality of portable mobile communication equipment (such as mobile phones, etc.) are greatly improved, and it has become an indispensable part of people's life. Missing belongings. When people use mobile phones, the antenna inside the mobile phone will bring radiation at one end. In order to limit the amount of radiation to ensure human health, the concept of SAR is often introduced. SAR (Specific Absorption Ratio, specific absorption rate) refers to a unit of time. The amount of electromagnetic radiation energy absorbed by a unit mass of matter. Internationally, the SAR value is usua...
