Meta resonator based lower S-band antenna for cube-satellite communication system

In the space program, Cube Satellite has gained popularity in terms of nanosatellites, which can build by applying available the-shelf components and leads to cost-efficient. This concept generated another phase in space technology that inspired many sectors i.e.: business industries, government agencies, and the military to invest in this field. Circular polarisation plays a vital role for the smooth operation of the Cube-satellite communication system. The article proposed a meta resonator-based defected ground S-band circular polarised antenna for CubeSat applications. The antenna is designed and analysed by Computer Simulation Technology (CST) software. The computational and measured results showed that the proposed antenna obtained-10 dB bandwidth from 2.025-2.065 GHz with a peak realised gain of 5.2 dBi at the resonant frequency. The antenna also depicted 3dB axial ratio at the entire operating band. These properties make the proposed antenna a potential applicant for applications of lower L-band satellite communication.
