Abstract

A novel multiband antenna which can be integrated into a laptop computer is reported in this conference. The antenna evolved from a dual-band inverted-F antenna vertically mounted on a ground plane of LCD panel. By adding four parasitic resonators which are shorted quarter-wavelength elements, the antenna can achieve wideband performance to cover GSM850/GSM900/DCS/PCS/UMTS and 802.11a/b/g. Simulation was performed here by HFSS to optimally design the antenna and then practical structure was also fabricated to verify the simulation results. The measured antenna parameters as well as radiation efficiency are presented to validate the proposed antenna.
