Embodiment

In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further described.It should be appreciated that specific embodiment described herein is only explaining this reality With new, it is not used to limit the utility model.

As shown in figure 1, the near-field communication aerial of the individual pen form of the utility model embodiment includes housing 10, aerial coil 20 and circuit board 30, aerial coil 20 is the planar coil that a circle conductor wire surrounds, and is fixed in housing 10, aerial coil 20 is set There is opening 21, circuit board 30 is provided with the first feed point 31 and the second feed point 32, electrically connected respectively with two end points of opening 21, this The planar coil that sample passes through individual pen is the function that near-field communication aerial can be achieved.

Specifically, aerial coil 20 is preferably rectangular in shape, housing 10 be electronic equipment center, the electricity of electronic equipment Chi Gai is covered on center surface, and edge of the aerial coil 20 along the inner side of housing 10 is set, and the surrounding of loop circuit plate 30, is made It is as far as possible big to obtain the area of aerial coil 20, and is not contacted with other hardwares on circuit board 30, and it is big away from radome etc. Block metal, battery cover preferably using the nonmetallic of plastics, avoid producing interference to aerial signal.Electronic equipment also includes electricity Pond, battery save the inner space of electronic equipment, and aerial signal will not be done in the region that aerial coil 20 surrounds Disturb.Opening 21 can be located on long side or the short side of aerial coil 20.Certainly in other embodiments, the shape of aerial coil 20 Shape can be the other shapes such as circle, ellipse.
