摘要：
A novel ultrahigh frequency (UHF) near-field radio frequency identification (RFID) reader antenna based on the triangular complementary split ring resonator (CSRR) structure is presented in this work. The antenna consists of a power divider and a triangular CSRR structure. The CSRR slots are etched on the bottom ground layer of the power divider. The uniform magnetic field over the antenna plane is generated by this configuration. The proposed antenna operates from 0.73 to 0.93 GHz, and a total impedance bandwidth of 200 MHz (S11<- 13dB) is obtained. And the proposed antenna exhibit uniform field distribution over the antenna plane. Besides, the antenna is compact compared to the loop and TWA configurations.
