Abstract
In this chapter a general numerical method has been presented that enables one to solve antenna problems involving conductors and dielectrics. While the formulation is applicable to arbitrary antenna shapes, the matrix formulation was provided only for axisymmetric configurations. The method was then used to investigate the radiation properties of three distinctly different antenna types. The circular microstrip patch antenna was selected to study the radiation mechanism of a typical microstrip antenna element. The wraparound antenna was chosen to show that the method can be used to design or analyse complex antenna candidates. The last example, i.e. the reflector feed, was included to show the design steps involving high-precision antennas with stringent amplitude and phase-pattern requirements.Keywords
