The analysis of microstrip antennas using the FDTD method

摘要

The object of this article is to demonstrate the use of the FDTD method in analyzing planar antennas. Yee's cell as a basic element of the characteristic of the field in the FDTD method and Yee's algorithm are presented. The question of source modeling and stimulation of antenna, boundary conditions and method of analysis of planar antennas' structure are also discussed. Some results of the use of this method have also been presented, as a confirmation of its accuracy and usefulness in the analysis of planar antennas.
