Abstract
In this paper, a new coplanar waveguide CPW (Coplanar Waveguide) fed circular waveguide for ultra-wideband UWB (Ultra WideBand) applications using High-Frequency Structure Simulator (HFSS) and Computer Simulation Technology (CST) software is presented. A comparison of modeling and simulations of disk monopole antenna is presented. The purpose of the research is to first determine the geometric parameters and material properties of the antenna, and then perform simulations using HFSS and CST programs. The task of the research is to evaluate the performance by modeling a new coplanar waveguide-fed circular disk monopole antenna for ultra-wideband applications and to compare the results obtained from these two electromagnetic simulation tools. Modeling of a new coplanar waveguide-fed circular disc monopole antenna for ultra-wideband applications used planar patterns and a coplanar waveguide-fed circular disc monopole antenna providing a wide frequency range. Antenna modeling method was used to solve the problem. High-frequency structure simulator and computer simulation technology have been widely used in microwave studio programs, accuracy in solving electromagnetic problems and antenna modeling. The following results were obtained. High frequency structural simulator and Computer simulation technology has been implemented between 2.3 GHz and 12 GHz. Key parameters such as reflection coefficient (S11), directivity pattern and gain coefficient were analyzed to evaluate the antenna performance. As a result of the research, a circular disk monopole antenna printed on a dielectric layer and fed by a 50 Ω coplanar waveguide on the same layer is digitally shown to provide an omnidirectional directivity pattern over the entire frequency range.
