Abstract
The utility model provides a wireless POS (Point Of Sale) machine, which comprises a shell, an internal antenna body and a suspension joint metal piece, wherein the internal antenna body is fixed in the shell; the suspension joint metal piece is arranged at the periphery of the internal antenna body and is electrically isolated with the internal antenna body, the internal antenna body is induced by the suspension joint metal piece and a coupling effect is generated, so that efficiency of wireless communication is enhanced. According to the utility model, energy of the internal antenna body is coupled through the suspension joint metal piece, a radiation pattern and an impedance of the internal antenna body are modified through the suspension joint metal piece, the coupling energy of the internal antenna body is obtained by the coupled suspension joint metal piece, and the integrated radiation area is increased, so that the efficiency of wireless communication is improved and promoted.
Description
[technical field]
The utility model relates to a kind of wireless POS machine, particularly a kind of wireless POS machine that promotes wireless telecommunications usefulness.
[background technology]
The radiofrequency signal power of radio transmitter output is transported to antenna through feeder line (cable), is radiate with the electromagnetic wave form by antenna.After electromagnetic wave arrives and receives the place, next (only receive very little very little a part of power), and deliver to radio receiver through feeder line by antenna.It is thus clear that antenna is to transmit and receive an electromagnetic important wireless device, does not have antenna also just not have wireless communication.Antenna is various in style, for using under the different situations such as different frequency, different purposes, different occasion, demands of different.
Wireless POS machine is realized wireless telecommunications through built-in aerial, and still, the coil paper influence that built-in aerial is printed in the wireless POS machine at present is serious; This coil paper is the thermoinduction coil paper, and when the antenna design was by coil paper, this kind kenel coil paper can absorb the energy of antenna institute radiation; And cause the antenna feed impedance skew to cause VSWR to squint thereupon; Reduced the radiation efficiency of antenna, when coil paper slowly uses when tailing off, when the space between coil paper and antenna slowly becomes big; The VSWR of antenna and the degrees of offset of impedance are obvious especially, will reduce the usefulness of antenna greatly.
[summary of the invention]
The fundamental purpose of the utility model is to provide a kind of wireless POS machine that promotes wireless telecommunications usefulness.
The utility model provides a kind of wireless POS machine, and it comprises housing, built-in aerial body and suspension joint metalwork, and said built-in aerial body-fixed is in housing; Said suspension joint metalwork be located at around the said built-in aerial body and with built-in aerial body electrical isolation, said suspension joint metalwork induction built-in aerial body also produces the intercoupling effect, strengthens the usefulness of wireless telecommunications.
Especially, said suspension joint metalwork is a Copper Foil.
Especially, said suspension joint metalwork is pasted on the housing inboard.
Especially, said suspension joint metalwork is pasted on hull outside.
Especially, said wireless POS machine comprises two or two above suspension joint metalworks, and the combination of suspension joint metalwork is arranged at around the built-in aerial body.
Compared with prior art; The utility model is through the energy of suspension joint metalwork coupling built-in aerial body; The radiation pattern of built-in aerial body and impedance all can obtain revising because of the suspension joint metalwork; And the suspension joint metalwork of coupling also obtains the coupling energy of built-in aerial body, and makes whole swept area become big, the lifting so therefore the usefulness of wireless telecommunications will improve.

Fig. 1 is the decomposing schematic representation of first kind of embodiment of the utility model wireless POS machine.
Fig. 2 is the combination synoptic diagram of Fig. 1.
Fig. 3 is the structural representation of second kind of embodiment of the utility model wireless POS machine.
[embodiment]
See also Fig. 1 and shown in Figure 2, the utility model provides a kind of wireless POS machine, and it comprises housing 10, built-in aerial body 20 and suspension joint metalwork 30, and said built-in aerial body 20 is fixed in the housing 10; Said suspension joint metalwork 30 be located at around the said built-in aerial body 20 and with built-in aerial body 20 electrical isolation, said suspension joint metalwork 30 induction built-in aerial bodies 20 also produce the intercoupling effect, strengthen the usefulness of wireless POS machine wireless telecommunications.Wherein, The shape of suspension joint metalwork 30, position are relevant with the model and the position of built-in aerial body 20, and in present embodiment, the shape of built-in aerial body 20 takes the shape of the letter U; Coil paper 40 is positioned at the both arms of built-in aerial body 20; Radiation pattern and impedance according to built-in aerial body 20 obtain: it is inboard and near the relative position place of the one arm of built-in aerial body 20 that suspension joint metalwork 30 is adhered to housing 10, can effectively improve the VSWR shift phenomenon, can let the enhancing efficiency of wireless telecommunications.In present embodiment, said suspension joint metalwork 30 is a Copper Foil.
See also Fig. 1 and shown in Figure 3, the bonding location of suspension joint metalwork 30 is different from the embodiment of Fig. 1 in the present embodiment, other internal structure such as Fig. 1.In present embodiment, said suspension joint metalwork 30 is pasted on housing 10 outsides and near around the built-in aerial body 20, can effectively improves the VSWR shift phenomenon, can let the enhancing efficiency of wireless telecommunications.In present embodiment, said suspension joint metalwork 30 is a Copper Foil.
The utility model is through the energy of suspension joint metalwork 30 coupling built-in aerial bodies 20; The radiation pattern of built-in aerial body 20 and impedance all can obtain revising because of suspension joint metalwork 30; And the suspension joint metalwork 30 of coupling also obtains the coupling energy of built-in aerial body 20; And make whole swept area become big, the lifting so therefore the usefulness of wireless telecommunications will improve.
The above; Be merely the embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field can expect changing or replacement in the technical scope that the utility model discloses easily, all should be encompassed within the protection domain of the utility model.In addition, the quantity that suspension joint metalwork 30 is set in the said wireless POS machine is not limited to one, also can comprise two or two above suspension joint metalworks 30, and 30 combinations of suspension joint metalwork are arranged at around the built-in aerial body 20.Therefore, the protection domain of the utility model should be as the criterion with the protection domain of claim.
