Abstract :
A system of integral equations (SIE) based on the uniqueness theorem that uses only electric equivalent currents is formulated to analyze problems composed of conductors and dielectrics. This SIE is solved using the moment method in its formulation for bodies of revolution for several short dielectric-rod antennas. Radiation patterns were measured to test the SIE formulation; excellent agreement between measured and calculated values was obtained
