Abstract
A compact coplanar waveguide-feed monopole antenna with dual-band characteristics is proposed in this article. The proposed antenna mainly consists of meander T-shaped monopole and small ground plane embedded with a pair of L-shaped couple slots and two pairs of I-shaped notched slots symmetrically. By elongating the meander T-shaped arms and carefully selecting the positions and lengths of L-shaped slot and I-shaped slot, the antenna excites four resonant frequencies at 2.42, 2.52, 4.75, and 5.54 GHz which are formed into two wide bands to cover all the 2.4/5.2/5.8 GHz wireless local area network (WLAN) operating bands, and is with miniaturization structure. Moreover, the antenna can provide nearly dipole-like radiation patterns and good gains across the dual operating bands. These results prove that the proposed dual-band antenna is very suitable for WLAN applications. © 2012 Wiley Periodicals, Inc. Int J RF and Microwave CAE, 2013. © 2013 Wiley Periodicals, Inc.
