A compact design of a hexagonal single feed circularly polarized microstripantenna for RFID applications is proposed. This structure fabricated on FR4 substrate offers compactness, good axial ratio bandwidth with a broadside radiation characteristic in the entire band, better gain, good impedance bandwidth at a resonant frequency of 2.45 GHz. The structure is suitable for RFID reader antenna applications
