RFID ELECTRONIC TAG AERIAL, ELECTRONIC TAG AND PROCESSING METHOD THEREOF

摘要

An RFID electronic tag aerial, electronic tag and processing method thereof; the aerial assembled on a substrate is designed as two portions extending in two directions, so as to reduce and attenuate at the welded end of the aerial the external force transferred from the substrate to a distal end or other force damaging the weld structure, thus improving the stress stability and anti-interference performance of the weld structure between the welded end of the aerial and the substrate, and improving the robustness of the RFID electronic tag in the entire life cycle. The RFID electronic tag comprises: a substrate, an electronic chip, and a set of aerials; the aerials have a first portion extending in a first direction, the first portion having several helical-shaped and consecutively-arranged spring rings; and a second portion connected to the first portion and helically extending in a second direction. The second portion is welded on the substrate, such that the aerials can be assembled on the lateral side of the electronic chip; and the first portion is in an elastic and unrestricted state in a plurality of directions relative to the second portion.
