摘要: ABSTRACT Radiation from a monopole antenna placed over an infinite size perfect conductivity ground plane and covered by finite height dielectric cylinder is examined. The axial symmetry of the structure excitation simplifies analysis. A two step approach applied to determine radiation properties antenna. In first place, elementary annular current source embedded inside determined. After determining Green's function, in second step, integral equation on solved Galerkin's technique compute distribution. Input impedances patterns are derived terms distribution Numerical results presented for several cases.
