Abstract: This paper presents a novel inkjet printed rounded corner bowtie antenna with T-matching stubs on paper substrate which is the cheapest and widest available substrate. The antenna exhibits compact size with outstanding read range and complete coverage of UHF RFID band (860-960 MHz). The results show extreme immunity of proposed antenna against paper dielectric constant variation.

Keywords: antenna, Inkjet printing, UHF-RFID, Paper substrate, Dielectric variation
