A Ku/Ka dual-band reflectarray has been developed as a demonstration model for the next generation of Titan cloud precipitation radar and altimeter (TCPRA). The reflectarray developed is a substitute of a parabolic cylindrical reflector and it is offset-fed by two linear arrays. The antenna has a 50-cm-square aperture and uses two 2-mil thick membranes for both bands enabling transformation into a...
This paper presents a novel antenna system that employs a "non- focused reflector" (NFR) to reconfigure the beams of communications payloads of HIEO (highly inclined elliptical orbit) and GEO (geo-stationary) satellites. The key advantages of the NFR are that it minimizes the number of feed array elements for a given coverage, has better scan performance, and has reduced complexity. Design...
