Abstract
This article presents a triple band hybrid cylindrical Ring Dielectric resonator antenna. The proposed antenna consists of Ring Dielectric resonator antenna and has a reformed pentagon shaped slot antenna. By the help of HFSS simulation software this proposed antenna has been designed. The return loss of the proposed antenna is -16dB, -20dB, -15dB respectively at frequency of 4.7GHz, 6.1GHz, 7.5 GHz respectively. The proposed antenna is applicable for c-band applications.
Highlights
Dielectric resonator antenna provides many benefits more than conventional antenna, these are fascinating antenna element such as high radiation frequency, low cost, small size, negligible metallic losses, flexible to different excitation arrangements and wider impedance bandwidth [1]-[3].Various applications namely video conferencing, wireless, direct digital broadcasting, radar and satellite applications
DRA wideband is attainment for low values of dielectric constant [2] as the bandwidth of the DRA is proportional to the dielectric constant
The DRA can be available in different shapes cylindrical rectangular, hemispherical [6]-[7]
Summary
Dielectric resonator antenna provides many benefits more than conventional antenna, these are fascinating antenna element such as high radiation frequency, low cost, small size, negligible metallic losses, flexible to different excitation arrangements and wider impedance bandwidth [1]-[3].Various applications namely video conferencing, wireless, direct digital broadcasting, radar and satellite applications. The DRA can be available in different shapes cylindrical rectangular, hemispherical [6]-[7]. During research work multiband featured such as pentagon, stair rectangular DRA are obtained from different shapes [8]-[9]. Out of these elementary shapes, cylindrical DRA is highly used because of its extensive commercial obtain ability and diversified radiation pattern
