Abstract

A novel printed dipole antenna with helix structure fed by a coplanar waveguide, suitable for 2.4 GHz and 5.2~5.85 GHz WLAN application is presented and investigated in this paper. The helix structure is designed so that the antenna length has a reduction then traditional printed dipole antenna. Some effects of many important parameters on the return loss and gain value of the proposed antenna have been investigated. In order to operate as WLAN device, the dipole antenna with helix structure should be cover the operation bandwidth of the 2.4 GHz and 5.2~5.85 GHz, and omni-directional radiation patterns are achieved at two operating bands.
