Description
Summary:In this paper, the radiation characteristics and the mutual coupling between two identical cylindrical dielectric resonator antennas embedded in a cylindrical structure in different configurations are calculated. To reduce the mutual coupling between the two antennas, the surface of the cylinder ground plane is defected by cutting slots, or inserting quarter wavelength grooves between the two antennas. The finite element method and the method based on the finite integration technique are used to calculate the radiation characteristics of the antenna.
