Compact Dual-Band Printed Folded Dipole for WLAN Applications

Miniaturization and multi-band operability have been the key desirable characteristic features of smart antennas designed in wireless communication. Printed folded dipole antennas find their applications in radio frequency identification tags. In this paper, a printed planar folded dipole antenna operating at 2.4 GHz is investigated to meet the requirements of miniaturization and multi-band functionality at 2.6 and 5.6 GHz. Altair Feko is used for the simulation of the antenna. The parametric study is performed to study the change in impedance bandwidth for varying dipole trace width and substrate thickness. The proposed antenna is found to be potential candidate for WLAN applications with dual-band functionality and omnidirectional radiation pattern.
