Embodiment
Fig. 1 is the explosive view of communication device of the present invention, and Fig. 2 is the schematic diagram of communication device of the present invention.It refer to Fig. 1, figure
2, communication device 100 includes loop aerial 110 and antenna carrier 120.Antenna carrier 120 is used to carry loop aerial 110, antenna
Carrier 12 0 has non-metallic areas 121 (dot-hatched), metal area 122 (linear shadow) and the first breach 123, the ring of metal area 122
Set around non-metallic areas 121, the loop coil of loop aerial 110 is arranged at non-metallic areas 121.In the present embodiment, annular day
Line 110 is made on flexible PCB, then flexible PCB is attached to the non-metallic areas 121 of antenna carrier 120, while by gold
Category area 122 is grounded.
There is the first basic point 1231, the first breach 123 is prolonged from the first basic point 1231 with first direction D1 on non-metallic areas 121
Extend the outward flange of metal area 122.That is the first breach 123 be the first basic point 1231 with it is a certain on the outward flange of metal area 122
Line between point, that is to say, that the first breach 123 destroys the globality of metal area 122, prevents metal area 122 from turning into
One complete sensing circulation.
In general, loop aerial, when work, the induced electromotive force of coil can produce opposite with the direction of the winding current
Reverse current, and caused reverse current can offset the coil current of part, so as to which the sensing capability of loop aerial can be reduced, but as schemed
Shown in 2, in the present invention, the first breach 123 destroys the globality of metal area 122, i.e., metal area 122 can not provide one it is complete
Whole sensing circulation, and in the case where sensing circulation is disconnected, induced electromotive force caused by loop aerial 110 is anti-induction electricity
Kinetic potential E ', and anti-induction electromotive force E ' direction can be identical with coil voltage E direction (such as counterclockwise), i.e., anti-induction is electronic
Faradic direction caused by gesture E ' can be identical with the direction of coil current, and induced-current is not only without the coil for offsetting part
Electric current, coil current is also add on the contrary, in this way, adding an antenna equivalent to loop aerial 110 strengthens induction coil, from
And enhance the sensing capability of loop aerial 110.In other words, compared with prior art, identical sensing capability (sensing capability
Power it is directly proportional to the size of coil current) require under, the volume of communication device 100 of the invention can be smaller, for example, show
It is that 50mm*40mm antenna can be only achieved 11cm sensing distance to have size in technology, and size is 30mm*20mm in the present invention
Loop aerial 110 is the sensing distance that can reach 11cm, and the volume of communication device 100 can greatly reduce.
In the present embodiment, further to reduce the volume of communication device 100, antenna carrier 120 can be communication device 100
Metal shell；And in other embodiments, the tabular of other metal-containing layers in antenna carrier 120 or communication device 100
Part, for example, circuit board etc..
In the present embodiment, the first basic point 1231 is located at the edge of non-metallic areas 121, and first direction D1 is horizontal direction,
And in other embodiments, the position of the first basic point 1231 may be alternatively located at the inside of non-metallic areas 121, and first direction D1 is alternatively
Other directions, such as 45 ° of directions etc., it need to only meet that the first breach 123 can disconnect the sensing circulation of metal area 122.
Above-mentioned antenna carrier 120 has a breach (the first breach 123), and in other embodiments, can also have
There are multiple breach.Fig. 3 is the schematic diagram of another embodiment of the antenna carrier of communication device of the present invention.Fig. 3 is refer to, antenna carries
Body 220 has non-metallic areas 221 (dot-hatched), metal area 222 (linear shadow), the first breach 223 and the second breach 224
(dot-hatched), metal area 222 are set around non-metallic areas 221.Non-metallic areas 221 has the first basic point 2231, the first breach
223 extend to the outward flange of metal area 222 from the first basic point 2231 with first direction D1, and the second breach 224 is from the first basic point
2231 extend to the outward flange of metal area 222 with second direction D2, and second direction D2 is in contrast to first direction D1, i.e. the first breach
223 are in a straight line with the second breach 224, can form the first breach 223 and the second breach 224 simultaneously, are not required to making
Also to control the length of breach during breach, it is more convenient on processing procedure.
As shown in figure 3, the first breach 223 can also fill nonmetallic materials, so that the both sides of the first breach 223 are better achieved
Insulation between metal area 222.And as illustrated, in the present embodiment, the first breach 223 is shaped as rectangle, and at other
In embodiment, the first breach 223 is alternatively the other shapes such as trapezoidal, and herein, the shape of the first breach 223 does not limit, only
It need to meet that the first breach 123 can disconnect the sensing circulation of metal area 122.
