One-dimensional beam scanning reflector antenna for small satellite applications

We propose a new compact center-fed reflector antenna with one-dimensional beam scanning function for small satellite application. The proposed antenna has different curves in orthogonal two cross sections. The beam scanning cross section is an imaging reflector form. The non-beam scanning cross section is an axial symmetry Cassegrain form. In this paper, we describe the design method of the proposed antenna based on a doubly curved reflector. The measurement of a prototype antenna demonstrates the validity of the proposed antenna.
