A New Resonant Frequency Tunable RFID Tag Antenna Design
A new resonant frequency tunable double-arm square spiral RFID tag antenna is proposed. It consists of two square spiral arms and two tunable stubs attached to the edge of them.The antenna shows 40MHz bandwidth under the condition of voltage standing wave ration (VSWR) less than 2,and can work at different UHF band standards from 840MHz to 960MHz by tuning the position of the two stubs at the end range of the square spiral arms. The dimension of the antenna is around 78mm×50mm and 1.76dBi gain is obtained by simulation.
