Abstract
The utility model relates to an anti-radiation antenna for mobile telephones, which is composed of a radiator and an antenna base. The technical problem that the utility model needs to solve is that electronic waves of an antenna in a horizontal direction are greatly attenuated so as to reduce the radiation to the human head. The lower part of the radiator is fixed in the antenna base, the antenna base is provided with a connecting piece which is connected with a mobile telephone, and the side of the radiator is provided with an absorption plate; the absorption plate is made of materials which can absorb telephone waves, and electromagnetic waves which are emitted by the radiator and radiate to the direction of the absorption plate are mostly absorbed by the absorption plate. Therefore, a safety angle is formed in one horizontal direction of the antenna, and the purpose of reducing the irradiation to users of mobile telephones is achieved.
Description
The utility model is a kind of radiation-resistant antenna of mobile phone handsets that is used for, the prior mobile phone antenna for mobile phone is the omni-directional antenna of making according to the requirement that mobile phone arbitrarily moves, its horizontal radiation bearing circle is near circular, easy to use, therefore but also make user's head be subjected to the influence of radiation.(patent No.: 93217428.0) sheath that uses metal material to make blocks or cries the method for reflection (screen we palpus ground connection) to existing a kind of technology, to prevent the radiation to the people of electromagnetic wave that mobile phone sends.Its shortcoming is this method with metal or other reflecting material reflection electromagnetic waves, the signal that easy interference handset sends, influence the standing-wave ratio of antenna, reduce the radiation efficiency of antenna, portion of energy can not be sent, become heat energy so that damage the mobile phone expelling plate, in addition, its shortcoming is to establish in addition on the mobile phone protective jacket, uses inconvenience also to influence attractive in appearance.
The purpose of this utility model is to overcome above-mentioned shortcoming, and is not only easy to use but also can reach the purpose of protecting the user.
The utility model is by radiant body (1), and wireless base (3) is formed, and the bottom of radiant body (1) is fixed in the antenna base (3), and antenna base (3) is provided with the connector that connects with mobile phone handsets, at the other baffle (2) that is provided with of radiant body (1) side.Baffle (2) is fixed on the antenna base (3).Baffle (2) is between head part and the radiant body (1) just, and radiant body (1) is fallen to the electro-magnetic wave absorption of head part's direction, reaches protection head part's purpose.
The utility model accompanying drawing is as follows:
Fig. 1 is the utility model antenna structure view.
Fig. 2 is contained in schematic diagram on machine for the utility model antenna.
Fig. 3 is for implementing illustration.
Structure of the present utility model as shown in Figure 1, radiant body (1) is by big line guard shield (4) institute cage lid,
One side of guard shield (4) is embedded with baffle (2), baffle (2) and protecting Cover (4) forms a circle, and radiant body (1) is in its center, and this circle is fixed On antenna base (3), link by antenna base (3) and mobile phone (5).
Above-mentioned baffle (2) is made with the magnetic composite wave-absorbing material, and this absorbing material wave absorbing efficiency is more than 20 decibels, and electromagnetic wave is during by it, will be absorbed by magnetic dipole wherein to become heat energy.Baffle (2) can be circular-arc; but enough width must be arranged; and should be longer slightly can produce an enough big safety angle than radiant body (1); to reach the purpose of protection; the used radiant body (1) of the utility model is as good as with existing mobile phone handset antenna radiation body in addition; antenna base (3) available metal material or plastics are made, and the rubber or the plastics of the available lower electromagnetic loss of guard shield (4) are made.
Advantage of the present utility model is simple in structure, and manufacturing and use are all easy, can prevent the infringement of electromagenetic wave radiation to human body head, and can not influence communication quality, can not damage mobile phone.
Embodiment: with an existing mobile phone handsets antenna as shown in Figure 3, coat magnetic absorbing material coating on a certain direction of its outer surface, coating is 120 ° as baffle (2) coating at the radian of horizontal plane.
Claims (4)
1, a kind of mobile phone is in the machine radiation-proof antenna, form by radiant body (1), wireless base (3), the bottom of radiant body (1) is fixed in the antenna base (3), antenna base (3) is provided with the connector that connects with mobile phone handsets, it is characterized in that the other baffle (2) that is provided with of radiant body (1) side.
2, mobile phone handsets radiation-proof antenna according to claim 1 is characterized in that above-mentioned baffle (2) made by the magnetic composite wave-absorbing material.
3, mobile phone handsets radiation-proof antenna according to claim 1, the shape that it is characterized in that above-mentioned baffle (2) can be circular-arc.
4, mobile phone handsets radiation-proof antenna according to claim 1 is characterized in that the length of above-mentioned baffle (2) is length than radiant body.
