Abstract

The Finite-Difference Time-Domain (FDTD) method is one of known electromagnetic numerical tool that used for design and analysis the antenna. Whereas this method is simpler than Method of Moments (MoM) or Finite Element Method (FEM) and it is space time based domain as a result benefited to wide band frequencies application. The purpose of project is to develop a simulator based on 3D-FDTD method for planar inverted F antenna. Hence the antenna dimension and characteristics such as relative dielectric permittivity, loss tangent and substrate thickness are directly entered by user into the MATLAB based-graphical user interface (GUI) menu which is user friendly and attractive. As a result of simulation the antenna electric field radiation are displayed into three (3) different planes. That radiation patterns can be partly drawn in xy, yz and xz plane at particular frequency. Since this software designed for three (3) dimensional antenna structure than two (2) dimensions, therefore higher computational cost. From this project, we had able create our own specific antenna software toward learning how commercial software such as that CST or HFSS developed. As well as learning tool to motivate for students keeps involving in development of antenna simulator or tool. Normally, prices of electromagnetic software packages especially antenna is quite expensive and license per year basis. Finally, this project also relevant and parallels with the latest technology in antenna design.
