Rectangular slot antenna design with two L‐shaped slits for WLAN/WiMAX applications

A novel coplanar rectangular slot antenna with dual band operation is proposed.By loading two dissimilar inverted L-shaped slit into the rectangular radiating element, broad impedance bandwidth at both lower and upper operating bands are achieved to allow the operation for 2.4/5.2/5.8 GHz wireless local area network and 2.6/3.5/5.5 GHz worldwide interoperability for microwave access bands. The design evolution of this proposed antenna by simulation is clearly demonstrated, and a prototype was fabricated and experimentally investigated. © 2011 Wiley Periodicals, Inc.
