Abstract

In this study, we designed and fabricated a multi-purpose planar antenna for DCS, WiBro, and ISM. The proposed antenna was designed an open-loop antenna that was transformed a monopole antenna structure. The capacitance of the multi-purpose antenna was increased by the coupling of open gap. This antenna has many advantages because of smaller size, lower cost, more lightweight, and higher gain than existing antennas. The resonance frequency and bandwidth can be adjusted by change of the gap and the height of the open-loop antenna. The bandwidth of the designed antenna is satisfied with DCS, IMT-2000, WiBro, Bluetooth, wireless LAN and ISM bands. The total frequency bandwidth is 58.75% and frequency range is 1.575 GHz ∼ 2.985 GHz (1.41 GHz). Also, the radiation pattern of the antenna was measured characteristics of co-polarization and cross-polarization at 1.6 GHz, 2.3 GHz and 2.8 GHz.
