This paper describes a compact high gain linear polarized printed Yagi antenna for a handheld UHF RFID reader that can be used in both Europe and US regions as well. The antenna is a Yagi type structure, with three elements (driver, director, and reflector) which fit into compact footprint (100 mm x 100 mm). The antenna has maximum gain of 5.3 dBi and VSWR is less than 2 in approximately 60 MHz band around European and US RFID bands (860 - 930 MHz). We describe the antenna structure and present the comparison of simulation results with experimental data.
