A semi-circle looped vertically omnidirectional radiation (VOR) patterned tag antenna for UHF ( 919–923 MHz for Malaysia) frequency is designed to overcome the impedance mismatch issue in this paper. Two impedance matching feeding strips are used in the antenna structure to tune the input impedance of the antenna. Two dipole shaped meandered lines are used to achieve a VOR pattern. The proposed antenna is designed for 23-j224 Ω chip impedance. The antenna is suitable for ‘place and tag’ application. A small size of 77 . 68×35 . 5 mm 2 is achieved for a read range performance of 8 . 3 meters using Malaysia regulated maximum power transfer of 2 . 0 W effective radiated power (ERP).
