Dual Band Microstrip Patch Antenna for WiMAX and WLAN ApplicationsDownload PDF
A dual band microstrip patch antenna has been designed for technology oriented requirements of high speed
wireless local area networks (IEEE 802.11a standard) and other communications systems covering the 5.15-5.825 GHz band. Three parallel slots have been introduced in the radiating patch to get the maximum current distribution on the surface. The position of center arm is set to get the radiation pattern in desired outward direction. The effects of various dimensional parameters were analyzed to get the optimized performance of the presented antenna. FR-4 substrate has been used for cost estimation whereas size reduction and enhanced gain of the structure was another challenge. To meet this challenge impedance is matched while maintaining the width of transmission line and also addition of slots is responsible for enhanced performance of antenna. The simulated results are good in agreement with measured results making antenna to be used for WiMAX and WLAN applications.
