Abstract
This article presents a new wideband slot antenna for wireless applications at 5.8 GHz. To improve the antenna bandwidth, a new feeding mechanism based on a capacitively- and inductively-coupled slot is proposed. To demonstrate this approach, an experimental antenna prototype operating at the 5.8-GHz band was designed, fabricated, and measured. The obtained results indicate very good agreement between the numerical and experimental results. The proposed antenna achieves a 28.5% bandwidth, a 5.7-dBi gain, and a −15-dB front-to-back ratio, which are very sufficient for broadband wireless applications. © 2005 Wiley Periodicals, Inc.
