Bandwidth Enhancement of W Slot Microstrip Antenna Using Stacked Configuration

In this paper, bandwidth of micro strip antenna is increased by introducing a slot of W shape and using stacked configuration. The proposed W slot MSA is suitable for high speed WLANs applications. By using different approach of bandwidth enhancement such as stacked configuration, cutting slot and changing the position of the coaxial probe bandwidth equal to 25.78% is achieved. The antenna is fed by coaxial probe feeding technique. The designed antenna operates in the frequency range of 4.381GHz to 5.668GHz covering the WLAN frequency band of 5.15 GHz -- 5.35 GHz. The antenna is designed using air as a dielectric substrate between the two layers and simulated on the Zeland IE3D software.
