A Design and Fabrication of Rectangular Slot Antenna for UWB-BAN Applications

Abstract

Body area network becoming a promising technology for a rapidly growth of a wireless medical applications. The ultra-wideband technology takes a vast attention by many developers due to an impulse radio transmission system. Therefore, the ultra-wideband gain big advantage to use for a wireless body area network application. This paper aims to design and fabricate a novel wideband antenna that can operate in the high-band of the ultra-wideband technology regarding to the Japan's regulation for the ultra-wideband technology, i.e., 6.5 GHz - 11.5 GHz. A rectangular slot antenna with line slit fed by a coplanar waveguide is proposed in this paper. The antenna structure is simply made on a FR-4 Epoxy substrate with a dimension of 30 mm x 35 mm x 1.6 mm (W x L x H). The results are show as a comparison between a simulation and measurement, which clearly seen a good characteristic of the proposed antenna. Hence, the proposed antenna is good to use for the body area network applications with the ultra-wideband technology.
