The optimal excitation voltage for spherical slotted antenna coated by two layers of dielectric material and plasma

Abstract

the optimal excitation voltage for spherical slotted antenna coated by two layers of dielectric material and plasma was analyzed numerically in this paper. By utilizing the Integra-functional equations method, the effect of excitation voltage across the slot on the radiation pattern are analyzed here by MATHCAD. Adjust the excitation voltage on a certain value can helps improve the radiation pattern for antenna and for more efficiency, the value of excitation voltage across the slot should be less than the value of electrical permittivity for plasma layer.
