Design of SWB Antenna with Triple Band Notch Characteristics for Multipurpose Wireless Applications

A compact concentric structured monopole antenna for super wide band (SWB) applications with triple notch characteristics is designed and experimentally validated. The covers an immense impedance bandwidth (1.6–47.5 GHz) sharp bands at 1.8–2.2 GHz, 4–7.2 9.8–10.4 GHz to eliminate interference from co-existing advanced wireless services (AWS), C bands, X respectively. By loading E-shaped stub connected the top of patch by etching a split elliptical slot lower end radiating patch, rejection AWS are achieved, Further, making use C-shaped resonator near feed line, obtained. varying parameters antenna, controlled independently over range frequencies. provides good radiation characteristics, constant group delay response, better gain pass band. experimental results indicate that offers remarkable reduction in high variation stop bands. To characterize wideband property linear phase response its time-domain performance extensively described evaluated, which assure pulse transmission minimum distortion.
