Abstract

In this paper, we propose the antenna to appropriate for a UWB communication system, and it meets characteristics for location recognition in predetermined range. Proposed tapered slot antenna was designed through the HFSS simulation tool of Ansys. Inc., it was produced by Taconic TRF-45 based on dielectric constant of 4.5, loss tangent 0.0035, thickness 1.62mm. The tapered slot antenna is analyzed the standing wave ratio and reflection coefficient, radiation pattern in the frequency domain. The impedance bandwidth range of the produced tapered slot antenna is from 3.8 ~ 8.9GHz to 5.1GHz, E-plane and H-plane radiation pattern meet directional antenna characteristics for indoor and outdoor location recognition in predetermined range. The antenna gain is 7.4 dBi(6GHz)in the simulation, the result of measurement demonstrated 7.4 dBi(6 GHz) of antenna maximum gain. Proposed tapered slot antenna meets UWB communication system but simulated and measured results were slightly different.
