Abstract

A double-fed printed monopole antenna having a wideband characteristic is presented. The monopole is rectangular in shape and is fed by a 50 ohms two-branch microstrip line. The antenna is designed and prototyped on a FR4 substrate. Both the simulated and measured results for impedance bandwidth are presented together with measured radiation patterns. The impedance bandwidth of the antenna is 2.2 GHz to 7.5 GHz covering all WLAN bands and frequencies in between. The antenna possesses approximately.omni-directional radiation properties throughout this bandwidth. It is easily fabricated using low-cost printed circuit technology. In addition this antenna is mechanically stable and readily Integratable with various mobile and portable devices.
