DRA, Stacked Antenna, Satellite Communication, Coaxial CableAbstract
The stacked antenna in which one SDRA (square dielectric resonator antenna) and one CDRA (circular dielectric resonator antenna) has been formed. The current stacked DRA has been designed in CST replication software for FSC (fixed satellite communication application). The antenna measurements are studied for given patch antenna with single DRA, but as expected these antennas give reduced radiation efficiency and low gain but after using stacked DRA, gain and efficiency has been enhanced. In current antenna coaxial cable feeding has been used which increases the efficiency at high frequency range. The current design obtains 6.5 dB of gain and 6.8 dB of directivity at 27.5 GHz frequency. The radiation efficiency is 96% and total efficiency is 94%. The current stacked DRA antenna operates perfectly in between 26-30 GHz and gives the best results at 27.5 GHz frequency.
