Abstract

Modeling is the foundation to design the dielectric resonator antenna by following our own specifications. Since it is very important, this project will discover the modeling of the resonant frequency and the radiation Q factor for a cylindrical dielectric resonator antenna. There are two types coupling that will be implemented in this project which microstrip line coupling and coplanar waveguide coupling. As for microstrip line coupling, the material of Cylindrical Dielectric Resonator Antenna (CDRA) been use is carbon and for coplanar waveguide coupling is CCTO (CaCu3Ti4O12). A thin layer of metal will be placed on the top of CDRA for both coupling. The designing process accomplished by using Computer Simulation Technology (CST) software. Agilent software will be involved in the analysis stage. The modeling process involved by using the result of the return loss of the simulation. Microsoft Excel will be used to record and plot the data of the return loss. By using the plotted graph, the curve fitting method will be used to generate the general equation of polynomial expression. Based on the polynomial expression, the value of the parameters will be altered in order to obtain the model that as close as the result of the simulated return loss. The 6th order polynomial has been chosen to be the model since it produces very accurate result.
