Abstract
The utility model relates to a double-frequency card used for wireless radio frequency, comprising a card body, wherein a high frequency antenna and an ultrahigh frequency antenna are fixed in the card body. The double-frequency card is characterized in that the ultrahigh frequency antenna is laminated on the high frequency antenna. With a reasonable structural design, the double-frequency card can reduce mutual interference between the high frequency antenna and the ultrahigh frequency antenna to a lowest degree, and can improve distance for a card reader to read individual frequency information so as to satisfy demands of a user.
Description
Technical field
The utility model relates to a kind of double frequency card that is used for less radio-frequency.
Background technology
Less radio-frequency (being Radio Frequency) is a kind of contactless automatic identification technology, and the work of identification is to need not manual intervention, is playing the part of very important role in the life of this Technology in Modern.No matter, all used widely at the still popular instantly wisdom mobile phone of space, medical treatment, amusement, traffic, telecommunication etc.Less radio-frequency has and is divided into three kinds, is respectively ultrahigh frequency, high frequency and low frequency.Over past ten years; High frequency (13.56MHz) has obviously improved operating efficiency on fields such as ticket, gate inhibition, stored value card, identity validation, driving license, I.D., passport and library; Great function has also been brought into play in be applied to logistics control, tracking or commodity inventory control, the antitheft etc. of ultrahigh frequency (880-950 Mhz) electronic tag in addition, so that double frequency card that high frequency and ultrahigh frequency are combined occurred.This combination has not only enlarged range of application, also highlights both complementary benefits.
The size of standard double frequency card is fixed, and just 85x76mm implants high frequency antenna 1' and ultra-high frequency antenna 2' in the little card of area space, does not disturb each other.General double frequency card structure has two kinds, and a kind of is to separate two antennas not contact, but antenna will limit to some extent.As split antenna with block major axis about two ends, or the card minor axis that is placed in up and down 2 half, like this, it just can only be half of card that respective antenna contains area, natural, it reads apart from just diminish.Another kind of mode is dwindled ultra-high frequency antenna, makes its coil that can put into high frequency antenna, also diminishes but the method lets ultrahigh frequency partly read distance.And these two kinds of employed antennas of frequency because of its principle of work and power is different, are combined in one, disturb each other easily, cause susceptibility not enough and can't be issued to user's requirement in many actual application environment.
The utility model content
The purpose of the utility model is to overcome the above-mentioned deficiency that exists in the prior art, and a kind of reasonable in design is provided, and can reduce the double frequency card that is used for less radio-frequency that interferes with each other between high frequency antenna and ultra-high frequency antenna.
The utility model addresses the above problem the technical scheme that is adopted: a kind of double frequency card that is used for less radio-frequency, comprise the card body, and at card body internal fixation high frequency antenna and ultra-high frequency antenna are arranged, it is characterized in that: described ultra-high frequency antenna is stacked on the high frequency antenna.
Described ultra-high frequency antenna one endlap of the utility model is on high frequency antenna one side.
The utility model compared with prior art has the following advantages and effect: 1, reasonable in design; 2, can reduce between high frequency antenna and ultra-high frequency antenna and interfere with each other, improve distance that CR reads the individual frequencies information to satisfy the user to minimum level.
Description of drawings
Fig. 1～Fig. 4 is the structural representation of 4 kinds of double frequency cards of prior art
Fig. 5 is the structural representation of the utility model embodiment 1.
Fig. 6 is the structural representation of the utility model embodiment 2.
Embodiment
Below in conjunction with accompanying drawing and through embodiment the utility model is done further to specify, following examples are to the explanation of the utility model and the utility model is not limited to following examples.
The utility model comprises card body 1, at card body 1 internal fixation high frequency antenna 2 and ultra-high frequency antenna 3 is arranged.
Embodiment 1: referring to Fig. 5, in the present embodiment, ultra-high frequency antenna 3 models are Alien 9962, and high frequency antenna 2 is of a size of 76 x 45mm.Ultra-high frequency antenna 3 both sides need shorten that each is half the, and it is stacked on the high frequency antenna 2, and is concrete, is that ultra-high frequency antenna 3 one endlaps are on the minor face of high frequency antenna 2 one sides.
Embodiment 2: referring to figure, and 6, in the present embodiment, ultra-high frequency antenna 3 models are UPM 208-2, high frequency antenna 2 is of a size of 76 x 45mm.Ultra-high frequency antenna 3 is stacked on the high frequency antenna 2, and is concrete, is that ultra-high frequency antenna 3 one endlaps are on the long limit of high frequency antenna 2 one sides.
In the manufacturing process, when pressing card, stack two groups of antennas up and down, but must be noted that the position of two groups of antennas, if relative position is incorrect, two groups of serious mutually interference of antennas will cause reading apart from dwindling significantly, even can't read at all.Therefore ultra-high frequency antenna 3 one ends need be stacked on the side of high frequency antenna 2 (plain conductor of a circle circle sealing).Certainly all need the media isolated of one deck insulation in the middle of the antenna of these plain conductors, high frequency antenna 2 has the PET mould, so overlappingly can not disturb because of short circuit together.The double frequency card that the double frequency card be pressed into and prior art be set according to this relatively, can provide stable read and do not have read single-frequency or two frequencies and all read the situation generation that obtains.High frequency 13.56MHz reads distance and is retained in 0～10 centimeter (CR NXP PERGODA), and ultrahigh frequency is read apart from also being retained in 0～6 meter (CR THING MAGIC).
Claims (2)
1. a double frequency card that is used for less radio-frequency comprises the card body, at card body internal fixation high frequency antenna and ultra-high frequency antenna is arranged, and it is characterized in that: described ultra-high frequency antenna is stacked on the high frequency antenna.
2. the double frequency card that is used for less radio-frequency according to claim 1 is characterized in that: described ultra-high frequency antenna one endlap is on high frequency antenna one side.
