Microstrip antennas are increasingly finding applications in microwave communication system as they are light weight, have planar configuration and inexpensive to fabricate. For many years, Ultra-Wide Band (UWB) antennas have had many applications in communication systems with broadband and spread-spectrum features in radar systems. This paper deals with a new compact Ultra-Wide Band (UWB) antenna using coaxial probe feed technique by introducing some slots in square patch of 20mm X 20 mm. The proposed antenna is designed to operate from 1.82 to 3.72 GHz with the centre frequency at 2.20 GHz. Size reduction of 83% is also achieved in this paper. Theoretical investigations have been done by Ansoft designer software.
