DESIGN OF C-SLOT ANTENNA FOR WIDE BAND APPLICATIONS WITH STOP BAND OPEARTION

Antenna is a vital component in wireless application systems. Antenna is important for establishing effective communication between places at different location. The microstrip antenna can be used for wireless applications as it has features such as light weight, easily mounted and it is easy to mass produce. The antenna has been characterized experimentally in terms of impedance bandwidth and radiation pattern. This C-slot antenna deals with design and fabrication of Microstrip antenna for the Ultra Wide Band frequency operation which cover the wide band from 3.10 GHz to 10.60 GHz. The substrate material used is FR4 with thickness 1.6 mm having the dielectric constant ( ) of 4.4. The patch material is copper having thickness of 0.1mm. The different patch designs are considered for observation purpose majorly derived from the basic Monopole patch structure and the detail study of the antenna parameter such as Return Loss (S11), Radiation pattern, Bandwidth, Radiation efficiency, Gain etc. is done for each of the antenna design. Simulated and measured results are presents to validate the usefulness of proposed antenna stricture for UWB applications..
