Abstract :
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 future larger deployable structure. To show the scanning capability in the cross-track plane, the antenna utilizes the phased array feeds with one for broadside beam and the other for 20deg tilted beam along the focal line. Measurement results performed in the indoor anechoic chamber at Texas A&M University will be presented in this paper.
