A Single Feed Circularly Polarized RFID Reader Antenna with Fractal Boundary

摘要：

　　A single feed circularly polarized RFID reader antenna with Minkowski fractal boundary is proposed.A 2-itration Minkowski patch is adopted for antenna compactness and four rectangular slots are etched on the ground to improve the antenna performance.The simulation result shows that this antenna behaves good characteristics in the design band, which has a-10dB impedance bandwidth of 52MHz(906-958MHz),3dB (Axial Ratio)AR bandwidth of 12MHz(917-929MHz).This design shows that the antenna structure is simple, easy for manufacture and integration.
