Description
Technical field:
The utility model relates to a kind of plane gap label, belongs to short-wave communication tedhnology field, is suitable for the field of radio frequency identification in 800MHz ~ 1GHz frequency range.
Background technology:
Rfid system has a clear superiority in stored prod information, and product information is stored in the electronic chip of RFID label tag, the identity of identification product that can be unique.RFID technique has obtained sizable market share, and is widely used in and does not contact in paying.And Internet of things system is the developing direction of following article internet, RFID technique is then the indispensable ingredient of Internet of things system, in future ideality, each object of ours at one's side can pass through the network interconnection, location, process, RFID technique is then everything basis.
In the numerous application of RFID, under having many situations, RFID label tag wants note to overlay on high-k body surface, such as glass surface, ceramic surface, and requires reading distance far away.And common dipole antenna is owing to being covered on high dielectric constant body surface, antenna frequency will ensure at 900MHz, and antenna size can only be very little, and gain is lower.For these problems, the utility model devises a plane gap electronic tag be applied on high-k body surface, and frequency band is wider, distinguishes distant, and form is simple, can solve the problem easily.
Utility model content:
In view of this, the utility model provides a kind of plane gap label, described label is thin slice, be pasted onto during use on object, comprise antenna, chip and substrate, described substrate accommodates described antenna and chip, wherein, described antenna comprises rectangular radiation face and a pair T-shaped gap, described a pair T-shaped gap is positioned at the center of described substrate, described rectangular radiation face comprises the rectangular radiation face of diging up a pair T-shaped gap, and described a pair T-shaped gap is that mirror image is arranged, and described chip is positioned in the middle of a pair T-shaped gap.
Further, described antenna material can be copper or aluminium or silver slurry or electrically conductive ink.
Further, the material of described substrate can be fragile paper or polyvinylchloride or resin glue ABS or gather phenyl formic acid glycol ester PET or polyimide PI.
Further, the perps gap in described T-shaped gap can be rectangle, triangle, fold-line-shaped, the transverse joint gap in T-shaped gap can be rectangle, triangle, fold-line-shaped, realizes antenna and chip conjugate impedance match by the height of the perps gap in adjustment rectangular radiation face width degree, T-shaped gap width and T-shaped gap.
Further, the shape of described substrate can be that polygon is oval or circular.
Further, working frequency range and impedance by regulating the length in rectangular radiation face, the length of the transverse joint gap in T-shaped gap and the perpendicular chinky altitude in T-shaped gap to adjust antenna.
Further, the range of size of described substrate is long 90mm ~ 100mm, wide 20mm ~ 25mm.Fundamental purpose of the present utility model is to provide a planar slot antenna electronic tag be applied on high-k body surface, and distinguish distant, broader bandwidth, applicability is strong.
This label comprises antenna, chip and substrate, and the rectangular setting of described substrate, accommodates described antenna and chip, and wherein, described antenna mates with chip.Described antenna comprises rectangular radiation face and a pair T-shaped gap, and described a pair T-shaped gap is positioned at the center of described substrate.Described rectangular radiation face comprises the rectangular radiation face of diging up a pair T-shaped gap.Described a pair T-shaped gap is that mirror image is arranged, and described chip is positioned in the middle of a pair T-shaped gap.
Plane gap RFID label antenna of the present utility model, owing to having pair of slits in the middle of radiating surface, regulates gap width and length can easily regulate antenna frequencies and impedance, is easy to mate with chip impedance.Double slit gap structure makes label antenna bandwidth enlargement.Compare the gain of common dipole sub antenna form comparatively large, broader bandwidth, is about 1.6 times of dipole antenna form.Thus make RFID label antenna of the present utility model have wider bandwidth while guarantee far reads distance.
