Abstract

The invention discloses a micro intelligent label, which consists of a dielectric substrate, antenna patterns, a chip and a packaging body, wherein the dielectric substrate has a square thin plate structure; the antenna patterns are arranged on the front surface and the back surface of the dielectric substrate and consist of signal input bonding pads, grounding metal faces, zigzag feed-in lines, zigzag balun lines, spiral micro-strip radiating units and through holes; the length of each radiating unit is less than 1/4 of the wavelength at a working frequency of an antenna; the chip is one special for an intelligent label; a mounting position is arranged between two input bonding pads of a part face of the dielectric substrate; the packaging body is made of a square resin molded plastic packaging material, is arranged on the upper part of the part face of the dielectric substrate to envelope the chip therein and is combined with the dielectric substrate to form a cuboid structure, so that a high-reliability ultrahigh frequency micro intelligent label product is realized.

Description

technical field [0001] The invention relates to the field of radio frequency communication and the field of smart labels, in particular to a miniature smart label. Background technique [0002] In recent years, due to the continuous development of radio frequency electronic technology, especially the wide application of radio frequency electronic tags, people's way of life is gradually changing. Common radio frequency electronic tags are divided into two categories: active and passive in terms of power supply; in terms of carrier frequency, there are 125KHz (130KHz) low-frequency bands, 13.56MHz high-frequency bands, 433MHz, 915MHz ultra-high frequency bands , 2.4GHz, 5.8GHz microwave frequency band; the application of electronic tags is ubiquitous, so there are various shapes and products suitable for different application requirements, making people's life more convenient and efficient. [0003] In order to make radio frequency electronic tags more widely used in daily li...
