Abstract

In the past few decades there has been a huge growth in the wideband high-frequency communication systems. A compact size, high-efficiency antenna design with low conductor loss is essential for enabling high data rate communication in addition to other necessary requirements. In ecent years, Dielectric Resonator Antenna DRA) has evolved to establish its presence because of its incomparable low profile,light weight antenna, that provide wide bandwidth with low dissipation loss compared to microstrip antennas. The flexibility in choice of shape, relative permittivity and size enables a whole spectrum of operating frequency ranges (1GHz-40GHz), sizes, radiation patterns and bandwidths. In this project the investigation of dielectric resonator antennas are quantitatively realized by the design and evaluation of two Dielectric Resonator Antenna.The first is a stacked dielectric resonator antenna with operating frequency range 8.17GHz-12.55GHz and other is stacked dielectric resonator antenna with operating frequency range 7.81GHz-12.33GHz both in X-band applications. The hybrid mode is suitable for a broadside radiation pattern. The modes can be excited by feeding from microstrip lines and coaxial probes and the location of the excitation determines excited mode.Size, shape and permittivity of the DR element govern the resonant frequency.
