Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the module diagram of POS in the utility model some embodiments；
Fig. 2 is the structural representation of touch-screen and antenna in the utility model some embodiments.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the present utility model.
Fig. 1 shows the POS in some embodiments of the utility model, including body 50, antenna 20, touch-screen 10 and penetrates
Frequency circuit 30, touch-screen 10 are arranged on the surface of body 50, and antenna 20 is arranged on inside body 50, and radio circuit 30 is arranged on body
Inside 50.
Wherein, the front of body 50 sets the touch-screen 10, and touch-screen 10 is used to show and operated for user.Preferably,
Touch-screen 10 is electric resistance touch screen, and touch-screen 10 is using without iron frame structure.In certain embodiments, touch-screen 10 can also
For other forms, such as capacitance touch screen etc..
Antenna 20 is arranged on inside body 50, and specifically, antenna 20 is located at the bottom of touch-screen 10.With reference to shown in Fig. 2, antenna
20 include the first feed point 21, the second feed point 22 and conductive silver paste 23.Wherein, conductive silver paste 23 is arranged on the first feed point 21 and second
Between feed point 22, conductive silver paste 23 is set in coiled type along 10 weeks edges of touch-screen.The silk-screen of conductive silver paste 23 in the bottom surface of touch-screen 10,
The number of coils of conductive silver paste 23 is at least one circle, it is preferable that in the present embodiment, the number of coils of conductive silver paste 23 is two circles.
Radio circuit 30 is connected with antenna 20, and carries out signal transmitting and receiving and processing by antenna 20.Specifically, radio frequency
Circuit 30 is connected by the first feed point 21 and the second feed point 22 with antenna 20.Preferably, between radio circuit 30 and antenna 20
It is connected by a FPC40, radio circuit 30 is onboard circuit.I.e. radio circuit 30, FPC40, two feed points are sequentially connected, from
And radio circuit 30 is connected on antenna 20.Such benefit is, in the antenna of onboard radio circuit 30 and coiled type
It is connected between 20 by the FPC40 of flexibility, is easy to connect up and produces.
It should be noted that antenna 20 connects antenna to be non-, and antenna 20 is in coil form.Used on electric resistance touch screen 10
Conductive silver paste silk-screen antenna because touch-screen 10 to the non-absorption for connecing antenna field intensity signal, cause it is non-connect the potent fruit of antenna field compared with
Weak, Card Reader effect is poor.Reach good effect needs to be designed according to following parameter, the inductance value scope of its designing antenna
In 800nH-600nH, self-resonant frequency higher than 80MHz to be preferred.Design process is as follows：1. by conductive silver paste in touch-screen 10
The mode of upper setting-out, 1-3 circles are drawn along ragged edge, set feed point, feed point connection Network Analyzer is tested.2. calibration network
Analyzer, bandwidth 1MHz to 150MHz is set, calibration instrument simultaneously carries out the top that port extension are calibrated to coaxial cable,
It is shown as open circuit point after having calibrated during non-external device in network analyzer.3. antenna 20 and terminated line are disconnected, network point
The signal of analyzer joint and ground (middle for signal wire, outside be ground) are welded to the both ends of antenna feed point.4. survey
1MHz Frequency points are measured, and draw the inductance value of this point.5. corresponding Frequency point when measuring X=0, and draw the self-resonance frequency of this point
Rate.6. debug out suitable coil size and the number of turns, and trace width by portraying silver paste repeatedly.By Network Analyzer, test
The Antenna Design of the match parameter in accomplished principle is demonstrate,proved, solidifying silver paste antenna by special process according to this design screen factory exists
On TP.Such benefit is that can reduce the non-antenna assembly material connect by the present embodiment reduces antenna Material Cost, reduces
Cost is produced and processed, touch display screen is solved to the non-absorption for connecing field strength, causes the non-Card Reader that connects ineffective, ensure non-connecing property
Energy.
