Design and Analysis of a Compact Ultra Wide Band Coaxial Probe Feed Microstrip Patch Antenna
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.
