A miniaturized dual-band antenna with spiral and meander lines for WLAN applications

A miniaturized dual-band antenna is proposed and investigated by combining spiral and meander lines for wireless local area network (WLAN) applications. The proposed antenna consists of a meander line and a spiral line, which are used to generate the bands of 2.37-2.58GHz and 5.11-5.96GHz. The proposed antenna fed by a 50-Ohm mini-coaxial line has a small size of 12.5×7.5 mm². The experimental results show that the proposed antenna can cover the required bandwidths for WLAN communication applications. Moreover, it can provide good omnidirectional radiation patterns and tunable dual-band characteristics, making it promising for practical WLAN communication applications.
