The analysis of the high frequency radiation pattern of an antenna mounted near an elliptic disk is the object of this research. This is an analytic study of basic antenna types using GTD ray optical techniques. The elliptic disk is modelled as a perfectly conducting flat plate and patterns are taken in the far field. An equivalent current modification is introduced to correct caustic and pseudo-caustic regions where the GTD solution fails. The validity of the solution is shown by comparing the predicted pattern against measured results. The elliptic disk solution can be used to approximate antenna patterns of antenna mounted near arbitrary cross-section flat plates. This solution can also be used as part of an elliptic cylinder solution for aircraft and ship models. Author
