Rfid chip for a belt and a belt

Abstract

The utility model discloses a kind of RFID chips for belt, including PET base material, antenna and chip;Antenna made of aluminum foil is set on PET base material by etching;Antenna includes rectangular body, and the middle of body is provided with hollow radiating area;The feeding port that makes antenna partition is equipped with in the lower of radiating area;Conductive glue layer is coated at feeding port;Chip, conductive glue layer, feeding port are fixedly connected by heat pressing;The long side of body is: 60-65 mm;The short side of body is: 5-7mm;The long side of radiating area is: 30-33mm, and the short side of radiating area is: 3.5-4.5mm;The interval distance of feeding port is 0.1-0.15mm.After using this scheme, antenna is designed into small-sized surface antenna, so that it can be conveniently fixed on the inner side of belt, or outside or built-in in the interlayer of belt.Guarantee reading effect while also realizing the reduction of chip volume, reading distance can still reach 1.5 meters.
