| Abstract: | The electromagnetic field expressions and eigenvalue equation of surface wave of microstrip antenna fed by coaxial line were deduced. By combining genetic algorithm (GA) and parameter tracking scheme (PTS), a new algorithm was developed and the eigenvalue equation was solved accurately. The computing results were agreeable with the available ones. The algorithm presented is of some advantages, such as simpleness, generalization, and precision etc. |
| Keywords: | microstrip antenna surface wave genetic algorithm |
