Abstract
An analysis of the offset Fresnel lens antenna is presented using the vectorial Kirchhoff diffraction theory. Equations for predicting the c opolarised and crosspolarised radiation patterns are given. Two approa ches to evaluating the far-field integration are introduced. Antenna p erformance such as the sidelobe and the cross-polarisation levels is i nvestigated. An experimental offset Fresnel lens is reported. Measured results agree well with the theoretical prediction.
