Its disadvantages include: large thickness, not less than 5mm; large length, mostly more than 100mm, mostly about 150mm, and the working frequency is 900MHz frequency band
It is precisely because of the large size and low gain of the anti-metal electronic tag antenna that it is very inconvenient to use, thus limiting the application of metal tags in some fields, such as laptop management systems

Embodiment Construction
[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.
[0022] figure 1 It is a structural diagram of the anti-metal electronic tag antenna. As shown in the figure, the antenna is divided into three layers: the bottom layer, the top layer, and the middle layer. The bottom layer is a complete metal conductor, such as copper foil, forming the floor 1 of the microstrip antenna. The top layer is composed of three independent metal conductors such as copper foil, including two arms of the dipole antenna and a square pad 6, the first arm 2 of the dipole antenna and the main radiator 2 of the microstrip antenna are the same A piece of metal conductor, which is also the main radiator of the anti-metal electronic tag antenna of the present invention, the second arm 3 of the dipole antenna is short-circuited between the floors 1 through a hole. The square pad 6 is short-circuited with the floor 1 ...

The invention discloses a high-gain and small-sized metal electronic tag antenna, which is formed by combining a microstripe antenna and a dipole antenna, wherein the microstripe antenna consists of a ground plate (1) and a main radiator (2), and the dipole antenna consists of a first arm (2) and a second arm (3); the main radiator (2) of the microstripe antenna and the first arm (2) of the dipole antenna share the same conductor; and a direct current short circuit is formed between the ground plate (1) of the microstripe antenna and the second arm (3) of the dipole antenna. The structure of the antenna comprises a bottom layer, a middle layer and a top layer, wherein the bottom layer is the ground plate (1), the top layer comprises the two arms of the dipole antenna, the middle layer comprises an FR4 substrate material (4) and a through hole (7), the substrate material (4) is used for filling a gap between the bottom layer and the top layer, and the through hole is used for the electric connection of two solid bodies on two sides of the substrate material (4). The antenna intelligently combines the microstripe antenna and the microstripe antenna and realizes the direct attachmentof the electronic tag on a metal surface.
Description
technical field [0001] The invention belongs to the technical field of microwave communication, and in particular relates to an anti-metal electronic tag antenna. Background technique [0002] Anti-metal electronic tags, referred to as metal tags, are a type of tags with special application environments. This type of label is usually attached to the metal outer surface of other objects. The electronic label is composed of the inner inlay of the label and the package outside the inlay, such as a plastic shell. The inner Inlay of the tag usually consists of an antenna and a chip. Since the current chip suppliers can widely provide electronic label chips for global label manufacturers, the core competitiveness of electronic labels is concentrated in the antenna. [0003] The current anti-metal electronic tag antenna is generally a dipole antenna in the ultra-high frequency band. A dipole antenna usually consists of two arms of equal length, and the material of the antenna i...
