Abstract

A wideband monopole antenna using a parasitic branch is proposed for allowing operations at multiple frequency bands specified in GSM($824{\sim}894MHz$), PCS($1750{\sim}1870MHz$), WiBro($2.3{\sim}2.4GHz$), WLAN/ISM ($2.4{\sim}2.48GHz$) and SDMB($2.605{\sim}2.655GHz$). We have used two branch monopoles and the one parasitic branch. Prototype of the multiband antenna have been successfully implemented and good radiation characteristics the operating frequency bands have been obtained. The effect of a parasitic branch was also studied.
