Satellite communications play a vital role in the current era of communications. In directional communications, there is a huge demand for highly efficient directives, and a better antenna for effective communication is required for satellites. This paper primarily focuses on the design and analysis of a reflector parabolic antenna which is used for satellite communication. The proposed design of reflector parabolic antenna achieves higher gain and better directivity than existing works and is found more efficient with better impedance matched using an Ansys HFSS. Along with this, it also focuses on the offset configuration of the parabolic reflector antenna.
