Abstract :
A low-cost, miniature-sized and isotropic Ultra-wideband (UWB) antenna is presented. In this paper, we will use a 3D EM simulator, HFSS, to design antenna. We employ exposure and development process to fabricate the miniature antenna, which is fed by a microstrip line and built on a FR-4 substrate with size of 22mm × 38mm2. Via measurement, the antenna´s matching characteristics and radiation patterns were obtained. The frequency band designed by this study is from 3.1GHz to 10.6GHz, targeting for UWB applications. Return loss is under -10dB and the gain range of the antenna is from 2dBi to 3.3dBi in this frequency band. Meanwhile, radiation patterns comply with requirements.
