Dodecagonal circularly polarized patch antenna for RFID applications

A compact design of a single feed circularly polarized microstrip antenna for RFID applications is proposed. This structure fabricated on FR4 substrate offers an area reduction of 10%, minimum axial ratio of 0.5 dB, axial ratio bandwidth of 116 MHz ( 5%) with a broadside radiation characteristic in...

Description
Summary:A compact design of a single feed circularly polarized microstrip antenna for RFID applications is proposed. This structure fabricated on FR4 substrate offers an area reduction of 10%, minimum axial ratio of 0.5 dB, axial ratio bandwidth of 116 MHz ( 5%) with a broadside radiation characteristic in the entire band and a gain of 4.9 dBi, 10dB impedance bandwidth of 5.4% (130MHz) at a resonant frequency of 2.4168 GHz. The structure is suitable for RFID reader antenna applications.
