Investigation of a cylindrical dielectric resonator antenna excited with a higher order mode

The higher order resonant mode (HEM
_12δ
), in a cylindrical dielectric resonator antenna (CDRA) has been investigated in regards to using it for practical purposes. In this paper, we have addressed the effect of the dielectric permittivity and other antenna parameters on the impedance and radiation characteristics. The HEM
_12δ
mode is excited using a non resonating microstrip patch.
