A new wideband cylindrical monopole antenna is presented for multiple band applications. Multiple band property of the proposed antenna is achieved by adjusting the coupling structure with steps between the antenna base and the ground plane. The measured -10 dB impedance bandwidths are $1.74{sim}3.06GHz;and;5.59{sim}10.62GHz$, which can cover various kinds of wireless services, such as $PCS(1.75{sim}1.87GHz),;IMT-2000(1.92{sim}2.17GHz),;WiBro(2.3{sim}2.39GHz),;WLAN(2.412{sim}2.483GHz,;5.725{sim}5.825GHz),;DMB(2.63{sim}2.655GHz)$, High-band $UWB(7.2{sim}1.02GHz)$.
