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
