Abstract

In recent years, ultra wideband (UWB) technology has been drawing attention as a promising technology in order to materialize ubiquitous network. The third-generation (3G) and the fourth-generation (4G) smartphones which employ the UWB technology have been hot. This study reports on a multiband antenna, which covers 800 MHz for 4G, 2.0 GHz for 3G and 3.1-10.6 GHz for UWB, built into such a smart phone. In the results from investigation, both of the multiband antennas, designed and made on an experimental basis, showed the VSWR less than 2.0 at 800 MHz, 2 GHz and UWB bands. In conclusion, the multiband antenna developed in this paper is enough in practical use.
