Abstract
The invention relates to an antenna which comprises a grounding face, a radiation body, a feed part and a grounding part. The feed part and the grounding part are connected between the grounding face and the radiation body and arranged side by side. The antenna further comprises a closed guide ring connected with the grounding face. The guide ring and the radiation body are arranged in a spaced mode and arranged oppositely. The direction of gains can be guided through the guide ring, and the aim of controlling the gains is achieved; the SAR value can be effectively decreased, and meanwhile the antenna can keep the high communication capacity.
Description
Technical field
The present invention relates to a kind of antenna, particularly relate to a kind of antenna relating to electromagnetic wave absorption rate.
Background technology
SAR(Specific Absorption Rate, electromagnetic wave absorption rate) for describing the specific absorption rate value of mobile device, it is defined as: under the effect of external electromagnetic field, will produce induction field in human body.Because the various organ of human body is power consumption medium, therefore in body, electromagnetic field will generation current, cause absorbing and dissipative electromagnetic energy, the electromagnetic power that tissue absorbed or consumed that SAR is unit quality, along with the microminiaturization of mobile terminal and the development trend of ultrathin, the volume of antenna is more and more less, but its electrical property needs to meet omnidirectional's total radiant power simultaneously, omnidirectional sensibility, the index requirements such as specific absorption ratio, when ensureing total radiant power, be difficult to reduce SAR value, if the SAR value of user is excessive, can damage the health of user, therefore in existing technical specification, all strict specification is had to the SAR value that the antenna of mobile device produces.
Summary of the invention
The object of the present invention is to provide a kind of antenna that effectively can reduce SAR value.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of antenna, it comprises ground plane, radiant body, current feed department and grounding parts, described current feed department and grounding parts to be connected between ground plane and radiant body and to be arranged side by side, described antenna also comprises the guided rings closed be connected with ground plane, described guided rings and radiant body spaced apart and be oppositely arranged.
Inventive antenna also comprises the guided rings closed be connected with ground plane, described guided rings and radiant body spaced apart and be oppositely arranged, when antenna occurs that certain directive gain is stronger, if when now peak gain or stronger gain appear at this direction, and just in time facing to the health of people, guided rings can guide the sensing of gain, reach the object that gain controls, effectively can reduce SAR value, make antenna can keep good communication capacity simultaneously.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of inventive antenna.
Embodiment
Refer to shown in Fig. 1, inventive antenna 10 is IFA antenna, and it arranges on a substrate 20, and antenna 10 comprises ground plane 11, radiant body 12, current feed department 13, grounding parts 14 and guided rings 15,
Current feed department 13, grounding parts 14 and guided rings 15 three are arranged side by side and spaced apart, current feed department 13 and grounding parts 11 are connected between ground plane 11 and radiant body 12, guided rings 15 is a closed-loop, guided rings 15 and ground plane 11 link together, and spaced apart with radiant body 12, guided rings 15 and radiation are carried 12 and are in sustained height.
When this antenna 10 occurs that certain directive gain is stronger, if when now peak gain or stronger gain appear at this direction, and just in time facing to the health of people, guided rings 15 can guide the sensing of gain, reach the object that gain controls, reduce SAR value, make antenna 10 can keep good communication capacity simultaneously.
Although be example object, disclose the preferred embodiment of the present invention, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present invention disclosed in appending claims, various improvement, increase and replacement are possible.
