Abstract

A closed-form spatial Green´s function for a horizontal electric dipole embedded in a thick dielectric sheet is presented. The characteristics studied include the radiation impedance, and the induction and radiation fields near and far from the practical dipole. Printed antennas are modeled and the input impedances are obtained using this accurate and rapidly converging Green´s function. The results agree well with physical interpretations. Numerical results are obtained for a thick dielectric sheet, which provides a good mechanical support for practical printed dipoles.<>
