Abstract

A Few Years After The Early Investigation On Ultra-Wideband (UWB) Wireless System, Considerable Research Efforts Have Been Put Into The Design Of UWB Antennas And Systems For Communications. These UWB Antennas Are Providing Wireless Wideband Communications Based On The Use Of Very Narrow Pulses On The Order Of Nanoseconds, Covering A Very Wide Bandwidth In The Frequency Domain, And Over Very Short Distances At Very Low Power Densities. Over The Allocated Bandwidth (7.5 Ghz) Of The UWB System, There Exists Some Narrow Bands For Other Data Communication Standards, Such As At Frequency 3.69 Ghz For Wimax (World Interoperability For Microwave Access), And At Frequency 5.825 Ghz For WLAN (Wireless Local Area Network), Which May Be Cause Electromagnetic Interference With The UWB System. In This Project, A UWB Patch Antenna Is Proposed For Providing UWB Application. The Dual Band-Notched Function Has Rejection Characteristics At 3.5 Ghz For Wi-MAX At 5.5 Ghz For WLAN. The Aforementioned Antenna Is Designed Using CST Microwave 2014 Software. A Patch Antenna Is Used Because It Is Smaller In Dimension And Ease Of Fabrication And Conformity. The Basic UWB Antenna Is Taken. The Antenna Has The Shovel Shape Radiating Patch And Grounding Patch At The Back. By Etching Two Nested C-Shaped Slots In The Radiating Patch Band Rejection Is Achieved For Wi-MAX And WLAN.
