Anti-human body miniaturized electronic label and producing method thereof

Abstract

The invention discloses an anti-human body miniaturized electronic label and a producing method thereof. The electronic label comprises a label antenna, an antenna base plate and a chip, wherein the label antenna is a mixed-type antenna formed by combining a microstrip and a doublet, and the radiating surface and the grounding surface of the label antenna are printed on the antenna base plate by metal wires to be used for receiving and sending the signal of the electronic label; and the chip and the label antenna printed on the antenna base plate are bound together by a via hole to be used for identifying the electronic label. The technical scheme of the invention is particularly designed for the human body, has anti-human body absorption and remote identification, and can reduce the harm for the human body by electromagnetic waves when the human body wears the electronic label.

Description

technical field [0001] The invention relates to the field of electronic label manufacturing in the field of microwave communication technology, in particular to a human body-resistant miniaturized label and a manufacturing method thereof. Background technique [0002] At present, most access control systems require employees to wear electronic tags for attendance. If the electronic tag is affected by the human body when it is close to the human body, the performance will drop greatly, and the normal operation of the electronic tag cannot be guaranteed. This will increase the emission of the electronic tag. Energy will have a certain impact on the health of employees. Therefore, the impact of ultra-high frequency electromagnetic waves on the human body has become a matter of increasing concern. [0003] At present, the UHF frequency band on the market is used to wear electronic tags on the human body, which are generally packaged into card quality and meet international stan...

Problems solved by technology

[0009] This value can neither meet the conditions of being a good conductor with a dielectric constant much greater than 1, nor can it meet the conditions of a good medium with a dielectric constant much smaller than 1. Therefore, it shows that the human body will produce obvious absorption of electromagnetic waves in the 900MHz frequency band, resulting in The reading distance of the electronic tag is shortened when it is close to the human body, and the effective distance may be shortened from 8 meters to 1 meter, forming a gap
