Description
Technical field
The invention belongs to antenna, particularly a kind of wireless telecommunications dual-band antenna.
Background technology
Society moves towards the computerization of height gradually now, radio communication product miscellaneous and mechanics of communication also just develop rapidly, therefore many radio communication products also become the part of daily life gradually, especially now notebook computer needs to do the action of data transmission often, utilizes Wireless transmission mode then can simplify the puzzlement of many settings and wiring.Yet, must consider processing procedure, position configuration and the mounting means of antenna for the purpose that reaches wireless transmission, also must make antenna when carrying out the action of wireless transmission simultaneously, be not subjected to the influence of surrounding enviroment.Moreover, the antenna that generally is applied to notebook computer roughly has two kinds of the plate aerial of the shape of falling F and antenna of single dipole, these two kinds of antennas all can produce the operator scheme of 1/4 wavelength resonances, but because the plate aerial frequency range of the shape of falling F is less, so can produce very big restriction in the use, though and antenna of single dipole has bigger frequency range, then must possess broad ground plane in use, so still can cause sizable inconvenience and restriction in the limited usage space of notebook computer.In addition, above-mentioned two kinds of known antennas all only have the operating function of single band (2.45GHz or 5.2GHz), and then also are subjected to sizable inconvenience and restriction in the use.
Summary of the invention
The purpose of this invention is to provide that a kind of frequency range is big, little, as to be applicable to notebook computer wireless telecommunications dual-band antenna takes up room.
The present invention includes coaxial cable with signal line, be connected in the antenna modules of coaxial cable one end and be connected in the coaxial cable other end to joint chair; Antenna modules is the flexible circuit board of tool sheet metal, and etching forms signal region and access area on the sheet metal of flexible circuit board; Signal region is provided with the load point that is connected with the coaxial cable signal line, and is provided with the path is received and dispatched signal than length with first frequency band and the path of generation low frequency transmitting-receiving signal with the generation high frequency than weak point second frequency band in the load point extension.
Wherein:
Coaxial cable signal line outer rim is coated with the earth connection that is connected with the antenna modules access area.
Be provided with insulating barrier between the signal line of coaxial cable and the earth connection.
Antenna modules system is positioned the pivot surface of notebook computer screen and main body.
Antenna modules system is positioned notebook computer main body surface.
Because the present invention includes coaxial cable with signal line, be connected in the antenna modules of coaxial cable one end and be connected in the coaxial cable other end to joint chair; Antenna modules is the flexible circuit board of tool sheet metal, and etching forms signal region and access area on the sheet metal of flexible circuit board; Signal region is provided with the load point that is connected with the coaxial cable signal line, and is provided with the path is received and dispatched signal than length with first frequency band and the path of generation low frequency transmitting-receiving signal with the generation high frequency than weak point second frequency band in the load point extension.During assembling, be on the load point of signal line with the coaxial cable signal region that is electrically connected at antenna modules, producing low frequency transmitting-receiving signal and second frequency band produces high frequency transmitting-receiving signal for first frequency band; During enforcement, be that antenna modules is positioned on the notebook computer, coaxial cable is placed through in the notebook computer main body, and make the butt joint seated connection be located at also formation electric connection on the default wiring board in the main body; During use, often use frequency range because of the networking of general wireless zone and be 2.45GHz (2.40GHz～2.84GHz) and 5.20GHz (two frequency ranges of 5.15GHz～5.35GHz), and first frequency band of the present invention can produce the frequency that is about 2.45GHz, and second frequency band can be produced as the frequency of 5.20GHz, so the frequency range of the present invention's first frequency band and second frequency band can be contained two frequency ranges simultaneously, and then has the transmitting-receiving frequency of double frequency-band.Not only frequency range is big, and take up room little, be applicable to notebook computer, thereby reach purpose of the present invention.

Embodiment
As shown in Figure 1 and Figure 2, the present invention includes the coaxial cable 2 that antenna modules 1, an end be connected with antenna modules 1 and be connected in coaxial cable 2 other ends to joint chair 3.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, antenna modules 1 is the flexible circuit board 12 of tool sheet metal 11, and etching forms signal region 111 and access area 112 on the sheet metal 11 of flexible circuit board 12.
As shown in Figure 1 and Figure 2, coaxial cable 2 have the signal line 21 that is connected with antenna modules 1 signal region 111, be coated on the earth connection 22 of signal line 21 outer rims and be arranged at signal line 21 and earth connection 22 between insulating barrier 23.Earth connection 22 is the access area 112 that is connected in antenna modules 1.
To joint chair 3 is the other end that is connected in coaxial cable 2.
During assembling, be on the load point 1111 of signal line 21 with coaxial cable 2 signal region 111 that is electrically connected at antenna modules 1, producing low frequencies transmitting-receiving signals and second frequency band 1113 produces high frequencies transmitting-receiving signals for first frequency band 1112.Earth connection 22 is the access area 112 that is connected in antenna modules 1.
As shown in Figure 5, during enforcement, system fits in antenna modules 1 of the present invention on pivot 43 surfaces of notebook computer 4 screens 41 and main body 42, coaxial cable 2 is placed through in notebook computer 4 main bodies 42, and makes joint chair 3 is arranged in the main body 42 on the default wiring boards 44 and forms and electrically connect.Also can as shown in Figure 6 antenna modules 1 be fitted in notebook computer 4 main bodies 42 surfaces, and then can different user modes can be arranged according to user's demand difference.
Moreover, the networking of general wireless zone often uses frequency range to be 2.45GHz (2.40GHz～2.84GHz) and 5.20GHz (two frequency ranges of 5.15GHz～5.35GHz), and first frequency band 1112 of the present invention can produce the frequency that is about 2.45GHz, and second frequency band 1113 can be produced as the frequency of 5.20GHz, so the frequency range of the present invention's first frequency band 1112 and second frequency band 1113 can be contained two frequency ranges simultaneously, and then has the transmitting-receiving frequency of double frequency-band.
