Dualband Slot Loaded Circular Disk Patch Antenna for WLAN Application

Tunable dual frequency patch antennas provide an alternative to wideband antennas where large bandwidth is required for operation at two separate transmit-receive bands. When a micro strip patch antenna is loaded with reactive elements such as slots, stubs or shorting pin it gives tunable or dual frequency antenna characteristics. Recently, dual band antenna is found wide applications in wireless communication. The rapid development in WLAN technology demands the antenna having high performance, dual band and good radiation characteristics. Numerous slot antennas for 2.4/5GHz operations have been reported. Because of many attractive features, micro strip patch antennas have received considerable attention for mobile communication handset.
