Abstract :
The aims of the present study is to improve the bandwidth of the cylindrical dielectric resonator antenna (CDRA) excited by a coaxial probe above an finite ground plane by varying the permittivity of the CDR using an addition of a cylindrical sector. The permittivity and the size shape of the embedded element are varied in term to enhance the bandwidth and keep the minimum return loss. The finite element method (FEM) is employed to analyze the cylindrical dielectric resonator made from ceramic (constant εr=36.7).
