Abstract

A promising small-size WLAN antenna suitable to be mounted along the hinge of the ultrabook computer with metal housing is presented. The antenna is formed by a two-branch structure of a monopole strip and a loop strip. The antenna has attractive features of low profile and wideband operation. In addition, by using the closed resonant path provided by the loop strip, possible coupling of the proposed antenna with nearby conducting elements for frequencies over the 2.4 GHz band can be expected to be decreased. Also, when the antenna is operated in the 5.2/5.8 GHz band, the loop strip is not at resonance and can serve as a shielding element for the monopole strip. This can also lead to decreased possible coupling of the proposed antenna with nearby conducting elements over the 5.2/5.8 GHz bands.
