Abstract
The utility model discloses a microstrip antenna suitable for receiving and sending 2.4G antenna signals. The microstrip antenna is directly arranged on a circuit board. The microstrip antenna comprises a feed part contacting the surface of the circuit board, an earthing part and a radiating body, wherein the radiating body comprises a plurality of buckling radiating parts. By using the utility model, because of small antenna area, the circuit board is used for realized thoroughly, so the cost for moving handholding products is not increased; however, the area is small, and the mechanism area is not occupied.
Description
Technical field
The utility model relates to the antenna receiving-sending field, particularly a kind of microstrip antenna.
Background technology
Along with the development of society, the progress of mechanics of communication, communication products such as mobile phone have become the important communication tool of people.The use of simultaneous mobile phone is frequent day by day, and people are also more and more higher to the requirement of mobile phone.Not only need the volume of mobile phone more and more littler, and need the price of mobile phone more and more lower.
At present mainly with regard to two kinds of built-in and external antennas, built-in aerial objectively must be than a little less than the external antenna for antenna for mobile phone.Setting up of antenna all is as far as possible away from ground and building, and antenna is near with reference to ground the time, and most of energy will concentrate on antenna and with reference between the ground, and can't launch smoothly, so the antenna emission needs the space of " open as far as possible ".The mobile phone circuit version is exactly the reference ground of antenna for mobile phone, allows antenna away from other circuit of mobile phone, is the key that improves the antenna for mobile phone emission effciency.But, however, consider from the outward appearance demand of mobile phone, generally can select built-in aerial.
But present antenna all is welded on the wiring board plate as a device, therefore, not only takies the volume of mechanism, has also increased cost.
The utility model content
The purpose of this utility model provides a kind of microstrip antenna, and it can reduce the mobile phone volume, reduces relevant cost.
The utility model provides a kind of microstrip antenna, described microstrip antenna setting in the circuit board, described microstrip antenna comprises feeding portion, grounding parts and the radiant body that contacts with described PCB surface.
The radiant body of described microstrip antenna comprises some Departments of Radiation that bend shape that are.
The bending shape of the Department of Radiation of described microstrip antenna radiant body is made up of W shape, S shape and the U-shaped of plurality of continuous.
Adopt a kind of microstrip antenna described in the utility model, be applicable to the transmitting-receiving of 2.4G wireless signal, this microstrip antenna is set directly on the wiring board, it comprises feeding portion, grounding parts and the radiant body that contacts with described PCB surface, and the radiant body of described microstrip antenna comprises some Departments of Radiation that bend shape that are.Adopt the utility model,, do not increase the cost of ambulatory handheld product because antenna area is less, firm and hard existing by wiring board fully; And area is less, does not take mechanism's volume.
Description of drawings
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Referring to Fig. 1, Fig. 1 has shown a kind of microstrip antenna 100 described in the utility model, it is applicable to the transmitting-receiving of 2.4G wireless signal, described microstrip antenna 100 is arranged on the wiring board 200, and described microstrip antenna 100 comprises feeding portion 110, grounding parts 120 and the radiant body 130 that contacts with described wiring board 200 surfaces.The radiant body 130 of described microstrip antenna 100 comprises some Departments of Radiation that bend shape that are, and has shown first Department of Radiation 131, second Department of Radiation 132, the 3rd Department of Radiation 133 among the figure.The bending shape of the Department of Radiation of described microstrip antenna 100 radiant bodies 130 is made up of W shape, S shape and the U-shaped of plurality of continuous.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of above embodiment.
