Design of multi - based antenna for WLAN WIMAX and C-band applications

Abstract

Our paper presents a small, low profile, planar multi-band patch antenna for WLAN, WIMAX and C-band applications. The proposed antenna consists of two F-shaped fractal slots that are etched on either sides of the line feed and a defected ground plane. It is therefore compact in size and simple in structure. The measured bandwidths for 10 dB return loss are 98.1MHz, 237.6MHz, 289.3MHz and 1090.1 MHz with center frequencies 2.5GHz, 3.69GHz, 4.25GHz and 5.65GHz respectively, effectively covering S & C bands. Accessing the internet by simultaneously using WLAN&WIMAX standards and getting the satellite and mobile services have been the hallmarks of this design. To validate the proposed design, an experimental prototype has been fabricated and tested. Good agreement between measured and simulated results has been found. The designed antenna has been simulated in High Frequency Structural Simulator (HFSS) 13.0 by Ansoft.
