Abstract

In this article, a novel coplanar waveguide (CPW)-fed miniaturization folded slot antenna for wireless local area network (WLAN) application is proposed and investigated. The multi-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 designed antenna has a small overall size of 28 mm×30 mm, and operates over the frequency ranges, 90 MHz (2.40 GHz-2.49 GHz), 400 MHz (3.4 GHz-3.8 GHz) and 870 MHz(5.17-6.04 GHz) suitable for WLAN 2.4/5.2/5.8 GHz and WiMAX 3.5/5.5 GHz applications. The proposed antenna is developed, and its measured characteristics are in good agreement with the simulated results. The experimental results show that the antenna gives dipole-like radiation patterns and good antenna gains over the operating bands. In addition, effects of main parameters of the triple-frequency for the design on the electromagnetic performance are examined and discussed in detail.
