Abstract

In this article, a simple printed monopole antenna for dual-band WLAN applications in IEEE 802.11 b/g/a systems is presented. The proposed antenna with microstrip-fed structure is compact, which has a total size of only 18 mm × 28 mm × 1 mm. An experimental prototype has been fabricated and tested. The measured results show good dual-band operations with -10 dB impedance bandwidths of 9.1% and 36.2% centered at 2.43 and 5.55 GHz, respectively, which covers the 2.4/5.2/5.8 GHz WLAN operating bands. In addition, good antenna performances such as radiation patterns and antenna gains over the operating bands have been obtained. Numerical simulation results are in reasonable agreement with measured ones.
