Elliptic Slotted Antenna with Anisotropic Plasma Dielectric Coating

Abstract

Radiation properties of axially slotted elliptical antenna embedded in anisotropic plasma material are studied theoretically. The fields are expressed in terms of Fourier series with unknown constants. The radiated field constants are obtained using the boundary value method by invoking the boundary conditions at various surfaces. Results are plotted graphically for the radiation patterns for different geometries and electrical parameters. The results show that the presence of the anisotropic plasma coating has affected the main beam while elliptic antenna beam is less oscillated compared to circular one for the same coating thickness

“…The even and odd angular Mathieu functions are written in terms of Fourier series as (19) (20) Substituting equations (16) to (20) into equation (14), and can finally be written in terms of the slot field as…”

“…This solution can be used to show that the method of separation of variables can be employed to solve this type of problems effectively. Furthermore, the analysis presented in this paper, enables one to obtain exact solutions to radiation problems involving objects composed of other of types of materials [19][20][21][22][23].…”
