چکیده
A small size ultra-wideband (UWB) antenna having dimensions of 12x 19 mm 2 incorporated with dual bandrejected properties and good gain is recommended in this paper. The recommended antenna consists of a microstrip line fed rectangular-shaped patch with a circular slot on one side of FR4 substrate and rectangular DGS (Defected Ground Structure) on the other side. By etching a circle on the patch, dual band notch properties are obtained from 5.08 to 6.14 GHz WLAN band and 9.58 to 10.69 GHz. The recommended antenna has an impedance bandwidth ranges from 4.6 to 11.2 GHz. Simulation is carried out with HFSS software and measurements are carried out with E5071C Vector Network Analyzer. Simulated results are compared with measured results and they are in good agreement. We have observed there is no significant change in the return loss parameters even though the circular slot of same dimensions etched on ground. This suggested antenna can be used to overcome the Electromagnetic Interference (EMI) between UWB systems and WLAN systems.
