A new folded planar monopole antenna is proposed for multiband operations. Measured impedance bandwidth (VSWR<3) is 20% (820~1000MHz) and 119.8% (1570~ 6270MHz) in low and high frequency, respectively. The proposed antenna can effectively cover most mobile communication bands (CDMA, GSM, GPS, DCS, PCS, and UMTS), WiBro, S-DMB and WLAN.
