In this letter, the influence of the inherent distortion of source impedance in an RVS formalism on the S -parameter 11 evaluation of antenna structures is discussed. It turns out that the source model is not critical; one can decide the port ลฝ . impedance real or complex in the postprocessing stage

โฆ Synopsis
case, Figure 5 gives the radiation patterns at the resonance frequency obtained with different methods. From these patterns, it can be concluded that the hybrid FDTD leaky-wave method is more close to the FDTD method than the hybrid FDTD-ray method. As a result, the accuracy of the hybrid FDTD-ray method decreases when the transversal period enhance.
6. CONCLUSION
In this paper, two semianalytical methods for analysing the radiation patterns of Fabry-Perot cavities internally excited have been compared. The leaky-wave-based method produces more accurate results compared to the ray method without increasing processing time.
