A simple dual-band antenna using a meander line and a tapered rectangle patch for WLAN applications

This paper presents a simple dual-band antenna for wireless local area networks (WLANs) applications. The dual-band characteristics are obtained by the use of a meander line and a tapered rectangle patch. The upper band is given by the tapered rectangle patch that is connected to a 50 Ohm microstrip feed line, while the lower band is produced by means of a meander line that is integrated with the partial ground plane. The proposed antenna has a compact size of 35mm × 20 mm. The simulated results demonstrated that the proposed antenna can provide two resonance frequencies with a -10 dB bandwidth of 26.4% and 34% at lower band and upper band to cover both the 2.4-2.484 GHz and 5.15-5.825 GHz WLAN bands. The proposed antenna, having tunable dual-band characteristics, good omnidirectional radiation patterns and small size, is promising for practical WLAN communication applications.
