A compact dual-band folded-slot antenna for WLAN application

In this article, a coplanar waveguide -fed miniaturization folded-slot antenna for wireless local area network application is proposed. The two operating bands are achieved by folded-slot antenna with slot loading. The parametric analysis of the antenna is done by the available electromagnetic solver HFSS11. The proposed antenna is developed, and its measured characteristics are in good agreement with the simulated results. The measured impedance bandwidth for 10-dB return loss at 2.4 and 5.5 GHz operating band are 90 MHz (2.40-2.49 GHz) and 950 MHz (5.1-6.05 GHz), respectively. Furthermore, the antenna has a simple planar structure and occupies a small size of about 28 x 30 mm(2). The antenna also shows good radiation and stable antenna gains across the operating band.
