Abstract A reliable and low‐cost solution‐processing procedure to synthesize a highly adhesive flexible metal antenna with low resistivity for radio‐frequency identification device (RFID) tags on paper substrates via inkjet printing combined surface modification electroless deposition (ELD) is demonstrated in this paper. Through the of colloidal solution hydrolyzed stannous chloride chitosan solution, paper‐based substrate able reduce penetration rate ink further increase adsorption amount silver ions, which could create catalytic activating layer catalyze subsequent ELD conductive deposited antenna. The resulting RFID presents good strength 2.58 × 10 −8 Ω·m after 40 min ELD, maintains reading range even over 1000 times bending mechanical stress. Consequently, developed technology proposed allows cheap, efficient, massive production excellent electrical properties. Furthermore, process especially advantageous fabrication next‐generation electronic devices based substrates.
