A novel compact center-fed reflector antenna with one-dimensional beam scanning function

A novel composition and test results of a compact center-fed reflector antenna with one-dimensional beam scanning function has been demonstrated. The feature of the proposed antenna is that the sub-reflector differs in a caustic mutually. The doubly curve has been used for the shape of the reflector surfaces. The 20λ-size antenna has been fabricated and tested in x-band. As a result, measured value and calculated value were in good agreement. The composition of this antenna and the validity of the design method have been confirmed.
