Radiation Characteristics of Cylindrical Dielectric Resonator Antenna Mounted on Superquadric Cylindrical Body

Abstract

Characteristics of cylindrical dielectric resonator antenna on (CDRA) on superquadric cylindrical body are discussed in this paper. Curvature effects on radiation characteristics in different planes of (CDRA), the reflection coefficient, the input impedance, The co-polarization and the cross-polarization characteristics, gain of the antenna, are calculated and discussed for different values of ν "squareness parameter". Then show effect of changing the aspect ratio B/A on the reflection coefficient and the input impedance. The proposed antennas are numerically investigated using finite element method and the finite integration technique.
