It should be noted that the plate aerial 1 is connected with the NFC antenna 2 in the way of arranging female 3 row pin 4 and combining.
Preferably, in addition to metal-back；
The metal-back is provided with rectangular recess, for installing antenna assembly construction；
The plate aerial 1 is installed in the rectangular recess；
The NFC antenna 2 is installed on the plate aerial 1 by arranging mother 3 and row's pin 4.
NFC antenna 2 is fixed on the top of plate aerial 1, makes the spacing for probably having 7~9mm between the two.Keep this
Away from primarily to reducing influence of the NFC antenna 2 to plate aerial 1, NFC antenna 2 is too near to plate aerial 1, plate aerial 1
Centre frequency can be offset.
Refer to Fig. 2 and Fig. 3, according to simulation result, drawn by Fig. 2, plate aerial 1 and NFC antenna 2 relatively when,
When i.e. the distance between they are 3mm, maximum field strength is 0.38, and is drawn by Fig. 3, and plate aerial 1 and NFC antenna 2 are distant
From when, i.e., the distance between they be 8mm apart from when, maximum field strength is 0.56.Field strength is increased close to 1 times.Therefore, actual peace
During dress, in order to take into account the structure of door lock and the efficiency of antenna, should try one's best control the control of the spacing of two antennas 7-9mm with
It is interior.
Embodiment 2
A kind of antenna assembly construction provided in the utility model embodiment, including：Plate aerial 1 and NFC antenna 2；
The plate aerial 1 and the NFC antenna 2 are all tabular, are abreast combined, the plane of two plates is apart
7mm~9mm.
Referring to Fig. 4, the plate aerial 1 includes the first bottom plate 5, flat metal piece 6, microstrip line 7 and sub-miniature A connector 8；
The flat metal piece 6 is rectangle, is installed on first bottom plate 5；
The microstrip line 7 is installed with first bottom plate 5, connecting the flat metal piece 6 and sub-miniature A connector 8.
Preferably,
7 points of the microstrip line is two sections；
One section of connection flat metal piece 6 of the microstrip line 7, for Regulate signal transfer impedance to 50 ohm；
Another section of connection sub-miniature A connector 8 of the microstrip line 7.
Preferably,
The flat metal piece 6 is rectangle, and its length and width is 30mm ± 2mm.
Preferably,
The plate aerial 1 is specially 2.44GHz antennas.
2.44GHz antenna models use plate aerial 1, as shown in Figure 4.The length and width of flat metal piece 6 are by 2.44Ghz's
1/4 wavelength (30mm or so) is designed, and length and width will be adjusted suitably so that resonance is in 2.44Ghz or so at the feed of the sheet metal lower left corner.
Plate aerial impedance is general all larger, it is therefore desirable to introduce the microstrip line 7 of matching, band internal impedance is transformed into 50 Ω.Due to
The radiation direction of plate aerial 1 is in single side, and most of energy of electromagnetic wave is all that just direction is radiated toward flat board, is also just said flat
Plate antenna 1 can be placed on inside metal-back, as long as opening a groove on metal-back the energy of antenna can be made fully to give off
Come.If using common half-wave dipole antenna, because the radiation direction of antenna is omnidirectional, by the anti-of back metal shell
Projection is rung, and the impedance of antenna much deviates 50 Ω by being influenceed by the equivalent mutual impedance to reflecting surface.Although still can lead to
Toning, which is matched, causes the impedance of antenna to return to 50 Ω, but the effect that this method is recalled, can not be general, and day is altered slightly
The position of line, the size of metal-back, the size of fluting are accomplished by adjusting matching again.This can be then avoided completely using plate aerial 1
The problem of kind, because the original radiation direction of antenna just concentrates on front, as long as fluting keeps enough sizes, the energy of antenna
It can be radiate by fluting, neighbouring metal-back, in any case close to antenna, also less influences antenna.
Embodiment 3
