Abstract :
A simple printed-loop antenna with wideband characteristics is presented for laptop computer applications. The proposed rectangular loop pattern generates four resonant modes below 4 GHz. The excited modes, two unbalance and two balance, are analyzed and discussed. A novel U-shaped tuning element printed on the back side of the circuit board adjusts the resonant modes to cover GSM850/GSM900/DCS/PCS/UMTS/WLAN and WiMAX bands. Using HFSS software, this study conducted a simulation to optimize the antenna design and fabricate a practical structure to investigate its performance and characteristics. This study also measures various antenna parameters to validate the proposed antenna.
