Operation modes and characteristics of a plasma dipole antenna

Abstract

The existence modes of a surface electromagnetic wave on a plasma cylinder, and the operating modes and characteristics of a plasma antenna are studied in this paper. Solutions of the dispersion equation of the surface wave are obtained for a plasma cylinder of finite radius for different plasma density values. The operation modes of a plasma asymmetric dipole antenna of finite length and radius are researched by numerical simulation. The electric field distributions of the plasma antenna in the near field and the radiation pattern are obtained. These characteristics are compared with the characteristics of a similar metal antenna. Numerical models are verified by comparing the counted and measured metal antenna radiation patterns.
