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

Abstract

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 × 30 mm2. The antenna also shows good radiation and stable antenna gains across the operating band. © 2013 Wiley Periodicals, Inc. Microwave Opt Technol Lett 55:2753–2756, 2013

Compact Dual-Band Suspended Microstrip Slot Antenna with an Antipodal Parasitic Element for WLAN Applications

“…For example, slot antennas such as placing narrow meander slots in the corner region for lower frequency band and embedding dual slots with a bent edge for higher frequency band [1] or an L-shaped strip line in the modified bow-tie slot antenna with a rectangular tuning stub [2] are published for dual-band characteristic. In [3], a novel rhombus slot antenna for WLAN standards at 2.4, 5.2, and 5.8 GHz bands or a slotloading CPW-fed folded-slot antenna with dual-band operation [4] are proposed. Furthermore, a novel compact monopole antenna for WLAN applications is also proposed in [5], which consists of an L-shaped monopole radiator and an arc-shaped stub.…”
