Abstract :
Three notch bands are created in a CPW fed extremely wideband printed monopole antenna to avoid interference from other existing systems while providing multiple wireless services. The base antenna shows 2:1 VSWR bandwidth from 1.6 Ghz to over 26 Ghz. By incorporating a slot on the patch, another slot on the ground plane and a T-shaped metal strip at the back side of the substrate, three band notches are introduced in the VSWR bandwidth to prevent interference from WLAN (3.5 Ghz and 5.2 Ghz) and C-band satellite communication systems around 7.3 GHz. Gain remains fairly constant over the entire bandwidth with very low gain at the notched bands.
