Abstract
The present invention discloses a plane gap label. The label includes an antenna, a chip and a substrate. The substrate is disposed in a rectangle shape and receives the antenna and the chip, wherein the antenna matches the chip. The antenna includes a rectangle radiant surface and a pair of T-shaped gaps. The pair of T-shaped gaps is located at the center of the substrate. The rectangle radiant surface includes a rectangle radiant surface with the pair of T-shaped gaps dug out. The pair of T-shaped gaps is disposed in a mirror image manner. The chip is located between the pair of T-shaped gaps. The plane gap label is applied to the surface of an object with a high dielectric constant, long in reading distance, wide in bandwidth, and good in applicability.
Description
Technical field:
The present invention relates to a kind of plane gap label antenna, belong to short-wave communication tedhnology field, be 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 present invention 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.
Summary of the invention:
Fundamental purpose of the present invention is to provide a plane gap label antenna be applied on high-k body surface, is intended to note and overlays on the bandwidth that high-k body surface has larger recognition Distance geometry wider.
The present invention relates to radio frequency identification (RFID) field, provide a kind of plane gap label antenna be applied on high-k body surface.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 invention, 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 invention have wider bandwidth while guarantee far reads distance.
