Embodiment Construction

[0021] The specific implementation process of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] see figure 1 and figure 2 The UHF tag antenna 1 based on fractal processing of the present invention has a substrate 2 and a radiation plate 3 attached to the upper surface of the substrate and a substrate bottom plate 4 attached to the lower surface of the substrate, and the substrate 2 has a short-circuit surface 5 on both sides. The radiation plate 3 of the UHF tag antenna 1 based on fractal processing of the present invention has two amplitude oscillator units 31, 32, a chip 33 is arranged between the amplitude oscillator units 31, 32, and the amplitude oscillator units 31, 32 have undergone symmetrical fractal processing , using the space-filling property of the fractal theory, thereby reducing the resonant frequency of the tag antenna and reducing the size of the tag antenna.

Abstract

The invention relates to a UHF tag antenna based on fractal processing, which has a substrate (2), a radiating plate (3) and a bottom plate (4), and the radiating plate (3) has a first radiating oscillator unit (31) and a second Two radiation oscillator units (32), the first radiation oscillator unit (31) and the second radiation oscillator unit (32) are coupled by a chip (33), the first radiation oscillator unit (31) And the second radiation oscillator unit (32) has a fractal structure. The invention applies the fractal theory to the UHF tag antenna design, utilizes the space filling property of the fractal theory to form a radiation plate of a microstrip fractal binary array antenna, thereby reducing the resonant frequency of the tag antenna and reducing the size of the antenna.

Description

technical field [0001] The invention relates to a tag antenna, in particular to an ultra-high frequency tag antenna based on fractal processing. Background technique [0002] With the development and popularization of RFID (Radio Frequency Identification) - radio frequency identification technology, RFID, as a high-tech and message standardization basis for fast, real-time and accurate collection and processing of information, has been recognized by the world as one of the top ten important One of the technologies, with the gradual clarification of UHF UHF frequency band Chinese standards and the demand for logistics, intelligent transportation, digital scenic spots and other applications, people's needs for tracking and management of metal and non-metal assets in various fields have become increasingly clear. Such as ultra-thin, ultra-small, ultra-light label design. This puts higher and more complex requirements on the design of tag antennas. [0003] Although, with the ...
