Abstract :
By improving the manufacturing processes of the double-folded inverted-L antenna (DFILA), two new printed circuit broad types DFILAs, which are the horizontal printed DFILA and the vertical printed DFILA, have been proposed. The proposed antenna is low profile, lightweight and simple in structure. Both antennas perform right hand circular polarization with center frequency of 2.4GHz. Both antennas have impedance bandwidth of over around 7% (S11<;-10dB) and axial ratio of 2.5% (AR<;3dB). The gains of the two antennas are higher than 6.4dBi.
