Description
Summary:In this paper, we propose a new compact antenna design for applications where an ultra-wideband (UWB) frequency range is needed. The main features of the proposed antenna is the capability of generate a quasi-isotropic radiation pattern. For this case, the proposed antenna is designed to operate from 2.17 GHz to 2.68 GHz. The construction details of the conceived antenna are presented and discussed. The measurements of reflection coefficient and radiation pattern were made in UFCG/LEMA's laboratory. The experimental results have good agreement with the simulated one. The simulation was made using the CST - Microwave Studio. The antenna is of easy construction and has application in wireless system and network sensors, field measurement or electromagnetic compatibility (EMC).
