Abstract :
The circular polarized antenna composed of an unbalanced fed ultra low profile inverted L antenna and a L shaped slot is proposed for the reader antenna of the portable terminal of RFID. At UHF band from 915 MHz to 930 MHz, the S11 less than-10dB and the axial ratio less than-3dB are satisfied. In the numerical analysis, the electromagnetic simulator “WIPL-D” based on method of moment is used.
