Abstract: The characteristics of wire antennas mounted on complex conducting objects are analyzed by using the MoM.The wire antenna is modeled as a thin strip.Planar triangular patches are chosen to discretizated the surface of the objects and the strip.RWG basis functions are used to model the surface current.Some segmentation methods for the patches near the attachment point are introduced.We define the basis functions and voltage model on the junction.Some numerical examples are introduced to analyze the characteristics of the wire antennas on conducting bodies and validate this method.
