The main advantages of Saphire Stacked dielectric resonator antennas
(SSDRA) are listed below: The DRAs are characterized by a smaller form
factor primarily when the material selected for design has a high
dielectric constant. Since a conducting material is absent the SSDRAs
have a high efficiency of radiation when the material chosen has low
dielectric loss. This feature makes it suitable for applications in the
frequency range of 30 GHz to 300 GHz. It will have large impedance
bandwidth when the resonator dimensions and dielectric constant of the
material are selected properly. It can be excited using distinct
techniques which is helpful for various applications and also for
integrating the arrays. Various design techniques can be used for
controlling the gain, bandwidth, and polarization characteristics of a
DRA The main aim of the study is to design a rectangular dielectric
resonator antenna where the dielectric resonator is made of sapphire.
The objectives of the study are: To design a rectangular dielectric
resonator antenna; To use a sapphire material for the DRA; To test the
designed rectangular DRA for C-band applications; To conduct a
comparative analysis of the result
