Abstract :
The purpose of this paper is to investigate accuracy and advantages of the TLM method in a cylindrical grid enhanced with the compact wire model when the subject of modelling is a circular patch antenna with a coaxial feed. Obtained results representing S11 parameter are compared with corresponding results reached by the rectangular grid based TLM method for different mesh resolutions as well as with referenced measured results.
