Radiation pattern of a planar electromagnetically coupled coaxial dipole array mounted over a finite metallic reflected plate

摘要

An efficient numerical method is proposed to analyze the far-field of electromagnetically coupled coaxial dipole (ECCD) element, and then uniform physical theory of diffraction (PTD) together with the above method is applied to investigate the radiation pattern of a novel planar ECCD array mounted over a finite metallic plate. Finally, as an application to the above ECCD array, lower troposphere radar (LTR) is briefly introduced. The analysis procedure in this paper can also be expected for optimum design in the systems involving the ECCD array antenna.
