Abstract

Electromagnetic scattering and radiation characteristic of perfect conductor object composed of arbitrary shaped line

surface and volume is analysed by using integral equation and moment method.The unknown current at line

surface and volume is uniformly represented by RWG basic function.For the arbitrary line-surface

surface-surface junction problem

we give the uniform approach to search basic function and unknown associated with it based on current continuity condition.For the radiation problem

we give the method of setting source and calculating input impedance.The method is validated by the example of analyzing monopole and wide-band patch antenna.
