An analysis of the offset Fresnel lens antenna is presented using the vectorial Kirchhoff diffraction theory. Equations for predicting the copolarized and crosspolarized radiation patterns are given. Two approaches to evaluating the far-field integration are introduced. Antenna performance such as the sidelobe and the crosspolarization levels is investigated. An experimental offset Fresnel lens is reported. Measured results agree well with the theoretical prediction.
