Abstract :
A low-profile planar broadband tag antenna mountable on metallic objects for UHF RFID systems is presented. The antenna has a planar structure without the need of shorting pins or plates, which lowers the cost in mass production. By embedding the odd symmetric slots to the proposed antenna, two adjacent resonant modes are excited to enhance the operating bandwidth. The simulated half-power impedance bandwidth of the proposed antenna is 132 MHz (838-970 MHz) that covers the worldwide UHF RFID frequency bands (840-960 MHz).
