A design of Ku band hat feed reflector antenna used for satcom on the move

This article designs a Ku dual band ring focus hat feed reflector antenna for use in shipborne communication systems. By analyzing the relationship between feed pattern and antenna efficiency, and optimizing through HFSS-MATLAB-API simulation, suitable feed have obtained. Finally, simulation optimization and machining testing were carried out on the feed reflector antenna with a ring focus hat feed reflector. The results show that the antenna aperture efficiency can reach 70%, the VSWR is less than 1.5, and the impedance and radiation performance are both good, meeting the strict requirements of satellite communication for the pattern envelope.
