Introduction
A novel, very low profile and ultra-thin inverted 'E' shaped monopole antenna for WLAN /WiMAX applications in the laptop computer is presented.
The thickness of the antenna is only 0.2mm and is designed using only a pure copper strip of size 20 x 6mm2. The innovation of the design is miniaturized size and wider impedance bandwidth in dual band operation using two monopole radiating strips namely RS (inverted J) and PQ(inverted Z) along with open ended vertical tuning stub of size 4.5x1mm2 . The measured impedance bandwidth spanned as 11.24%(2.35-2.63)GHz in a lower band and 18.78% (4.92-5.94)GHz in the upper band for VSWR
Optimized Values
We follow this parameter and duplicate into xFDTD environment.
