An Ultra-wideband (UWB) patch coplanar waveguide (CPW) antenna with tri band notched has been presented. The proposed antenna consists to insert two different forms of slots in order to obtain triple-band-notch characteristics. By using two C-slots on the radiating patch two notched bands are achieved at 3.5 GHz for Worldwide Interoperability for Microwave Access (WIMAX), and C-band satellite communication systems at 7.5 GHz. A spiral shaped slot is etched on the feed line to obtain another notched band for Wireless Local Area Network (WLAN) at 5.8 GHz. The design uses FR-4 substrate with dielectric constant of 4.3 and thickness of 1.6 mm. The proposed antenna provides an operating frequency range from 3.5 GHz to over 18.9 GHz with voltage standing wave ratio (VSWR) <2, except the notched bands VSWR > 2. The antenna is simulated by CST Microwave Studio. Current distribution and radiation pattern characteristics of the antenna are also reviewed. showing tri-band notched characteristic can be provided by using two different slots to avoid interference of UWB band with the existing systems.
