Advanced Methods for Development of Microwave Antennas for Integration in Space-Based Radar Systems

The aim of this paper is to contribute to the conceptual design of advanced antenna devices, such as Horn-fed offset Cassegrain reflector antennas for implementation in space-based millimeter-wave radars. The results obtained from the comparative analysis of the reflection coefficient and the gain of a linear waveguide slot array and a pyramidal horn antenna, based on diagrams presented in the Antenna Magus software, can significantly support the development of more efficient radar systems for space applications.
