JCS_V6_N2_RP1 Design an ACS-Fed Multi Band Antenna for Wireless Applications Using Defected Ground Structure Shubhi Shukla G.S. Tripathi Pooja Lohia Journal on Communication Engineering and Systems 2277-5242 6 2 1 4 Asymmetric Coplanar Strip, Multiband Antenna, Defected Ground Structure (DGS), WiMAX, WLAN In this paper, an ACS-fed Multiband antenna is presented. The resulting antenna resonates at 2.4 GHz, 3.5 GHz, 5.5 GHz 2 covering the WLAN and WiMAX operation bands. The overall dimensions of antenna is 19×21 mm printed on FR4 substrate material of 4.4 dielectric constant and 1.6 mm thickness. The proposed antenna follows the uncomplicated design, compactness, and easy fabrication. The details of antenna and results are discussed in this work. The antenna is designed using HFSS v13.
