Abstract
AbstractThis article proposes printed dual‐band monopole antenna structures for Wireless Local Area Network (WLAN) applications in IEEE 802.11 a/b/g. The proposed antennas are fabricated on a low cost easily available FR4 substrate, which effectively covers both 2.4 and 5 GHz bands. The antenna structures are derived from an E‐shape dual‐band monopole antenna, which generates two separate resonant frequencies for the desired dual‐band operations. The one arm resonates at the 5 GHz band, whereas the other resonates at the 2.4 GHz band. The proposed antennas can easily be fed by using a 50‐Ω probe feed. The measured VSWR is <2 over the 2.4–2.5 GHz and 5.15–5.875 GHz. The radiation patterns indicate the suitability of these antennas for WLAN applications. © 2008 Wiley Periodicals, Inc.
