Thereby, the frequency-modulation flat antenna can be arranged in the desired equipment, and the hiding of antenna is achieved.
Description
Technical field
The utility model relates to a kind of Frequency-modulation flat antenna, be meant especially a kind of can in be built in the required equipment, and reach the Frequency-modulation flat antenna of hiding effect.
Background technology
Usually, existing design is announced " notebook computer with antenna " No. 454962 as the Taiwan patent gazette, and it includes:
One main body is used for handling electronic bits of data;
One display is connected with this main body, offers a storage tank;
One antenna, one end and this storage tank articulate, and can rotate to a stowed position or a use location; And
More than one shell fragment, be arranged at the other end of this storage tank pivot joint antenna, and this shell fragment side and this storage tank side articulate, and when this antenna rotated to this use location by this stowed position, this shell fragment was the axle center with its side with the storage tank pivot joint, to this storage tank inner rotary, this antenna is stretched out, and when this antenna rotates to this stowed position by this use location, this shell fragment is the axle center with the side that itself and storage tank articulate, in this storage tank, rotate, this antenna is folded.
Above-mentioned though " notebook computer " commonly used with antenna, antenna can be arranged at the outside display of notebook computer in mobilizable mode, and antenna can be concealed in the notebook computer, but because general broadcast receiver is to adopt unipole antenna (Mono Pole), its frequency range is 88～108MHz, because its wavelength=light velocity/frequency (frequency is got the about 100MHz of median), so wavelength is 3 to take advantage of 6 powers of 8 powers/100*10 of 10, drawing its wavelength is 3m.Be the Design of length of adopting 1/4 wavelength because of general radio antenna again, about 75 centimeters of the length of therefore general broadcast receiver unipole antenna.That is to say, if originally unipole antenna is contained on the notebook computer, this unipole antenna must be able to be pulled out 75 centimeters, therefore with this design commonly used, though it in antenna being concealed in the notebook computer, is the reception effect that keeps good when being to use, its antenna must be pulled out, so cause the inconvenience in the use, moreover with the notebook computer of present pursuit overall appearance design, the existence of this exposed antenna will influence the global design of notebook computer; So general existing design can not meet user's demand on reality is used.
Summary of the invention
Therefore, main purpose of the present utility model is can make in this Frequency-modulation flat antenna and is built in the required equipment, and makes this antenna reach hiding effect.
For reaching above-mentioned purpose, the utility model provides a kind of Frequency-modulation flat antenna, and it is made of a body and a feed-in element that is connected with this body.This body is provided with radiant element, and this radiant element periphery ring is provided with an earth element, and has a short-circuit line between this radiant element and earth element; And this feed-in element has a holding wire and an earth connection, and the holding wire of this feed-in element is connected with above-mentioned radiant element, and the earth connection of this feed-in element is connected with above-mentioned earth element.Like this, can make in this Frequency-modulation flat antenna to be built in the required equipment, and make this antenna reach hiding effect.
Owing to adopted the technical solution of the utility model, can make and be built in the required notebook computer in this Frequency-modulation flat antenna, and make this antenna reach hiding effect, the user then need not do the action of drawing antenna when using, can do the reception of signal, and built-in plate aerial also can not destroy the overall appearance design of notebook computer.

Embodiment
Seeing also Figure 1 and Figure 2, is respectively three-dimensional appearance schematic diagram of the present utility model, perspective exploded view of the present utility model.As shown in the figure: the utility model is a kind of Frequency-modulation flat antenna, and it is made of a body 1 and a feed-in element 2, can make to be built in this Frequency-modulation flat antenna in the required equipment, and make this antenna reach hiding effect.
Above-mentioned body 1 can be a flexible circuit board or printed circuit board (PCB), and this body 1 is provided with radiant element 11, this radiant element 11 forms on the body 1 in the mode of direct etching or punching press, and this radiant element 11 is continuous crippling shape, and these radiant element 11 periphery rings are provided with an earth element 12, this earth element 12 is the U type state that three limits surround radiant element 11, and this earth element 12 is except that grounding function, also has the function that reduces other electromagnetic riveting machine signal interference emission element 11, and between this radiant element 11 and earth element 12, have a short-circuit line 13, and can on this body 1, be coated with layer protecting film 14;
This feed-in element 2 can be a coaxial line or twisted-pair feeder, and this feed-in element 2 has a holding wire 21 and an earth connection 22, and the holding wire 21 of this feed-in element 2 is connected with above-mentioned radiant element 11, and the earth connection 22 of this feed-in element 2 is connected with earth element 12.Like this, constitute a brand-new Frequency-modulation flat antenna by said structure.
Seeing also shown in Figure 3ly, is assembled state schematic diagram of the present utility model.As shown in the figure: when Frequency-modulation flat antenna of the present utility model in when assembling, this body 1 directly can be arranged at display 31 inside of notebook computer 3, again the other end of this feed-in element 2 is connected with input on the motherboard, radiant element 11 on this body 1 is received after the signal, transfer to input on the motherboard by feed-in element 2, and reach the effect that receives signal, so, can make and be built in the required notebook computer 3 in this Frequency-modulation flat antenna, and make this antenna reach hiding effect, the user then need not do the action of drawing antenna when using, can do the reception of signal, and built-in plate aerial also can not destroy the overall appearance design of notebook computer 3.
