Abstract

A compact novel multi-band stereo-inverted F antenna (SIFA) is proposed for mobile telephone applications. Generally the planar inverted-F antenna (PIFA) is often made an internal element by using metal conductor sheet. The studied antenna configuration is different to traditional PIFA. Usually single-core wire is used to construct internal radiator of which the impedance bandwidth is often constricted. The design novel radiator in this paper has good impedance bandwidth ratio up to 33 percent. It is operated at triple-bands, Bluetooth (2.4 GHz), Unlicensed NII-5 GHz UNII-1 (5.125 ~ 5.25 GHz) and UNII-2 (5.25 ~ 5.35 GHz). The compact configuration requirement as well as good electric characteristics of wide-band can be achieved
