Printed Half - Circular Monopole Antenna for UWB Applications

In this paper, a printed half - circular monopole antenna fed by a simple rectangular Microstrip line is investigated. This antenna was designed on Taconic RF-30 (tm) substrate, High-frequency structure simulator (HFSS) that evolved over a period of years with input from many users and industries was used to design, optimize, and simulate this antenna. The structural properties and performance characteristics of this antenna is investigated through numerical simulations. Then the design process, parametric study, optimization as well as simulated results such as return loss, radiation patterns and VSWR are provided. We found that the -10dB return loss bandwidth of the simulated antenna is approximately 7.1GHz (3.2GHz - 10.3GHz). The proposed half - circular patch UWB Monopole antenna is having better performance and good bandwidth than the conventional circular patch UWB monopole antennas.
