dc.description.abstractUltra-wideband (UWB) antennas are one of the most important elements for UWB systems. With the release of the 3.1 - 10.6 GHz band, applications for short-range and high-bandwidth handheld devices are primary research areas in UWB systems. Therefore, the realization of UWB antennas in printed-circuit technologies within relatively small substrate areas is of primary importance. This thesis focuses on the design of a new UWB antenna based on coplanar technology. Compared with microstrip circuitry, coplanar technology achieves easier fabrication and wider antenna bandwidth. Two professional full-wave field solver software packages, HFSS and MEFiSTo-3D, are used as analysis tools to obtain antenna performances. A new printed-circuit antenna in coplanar technology for UWB systems is introduced. The frequency of operation is 3.1 GHz to 10.6 GHz with a VSWR < 2. Nearly omni-directional characteristics in vertical polarization are demonstrated at selected frequencies. Relatively good group delay characteristics are obtained and compare well with other published UWB antenna designs.en_US
