Series Solution to the Radiation from Slotted Antenna on Elliptic Cylinder Coated by Biaxial Anisotropic Material
关键词:
Axially slotted elliptic antenna, biaxial anisotropic material, Mathieu functions, series solution摘要
Radiation characteristics of an axially slotted circular or elliptical antenna coated by biaxial anisotropic material are investigated using series solution. The fields inside and outside the coating regions are expressed in terms of appropriate Mathieu functions with unknown field coefficients. The boundary conditions at the conducting and dielectric coating surfaces are invoked to obtain the unknown field expansion coefficients. Numerical results are presented graphically for the radiation pattern with various geometries and electrical parameters.
