Two-surface Lens Correcting Amlitude Distribution and Phase Error

Abstract

The article describes design of a microwave dielectric lens correcting cosinus amplitude distribution to Taylor and also corrects pahase aperture error. Presented technical parameters obtained by a prototype development piece indicate that this solution in many cases could be a suitable alternative to a corrugated horn or to a horn with dielectric core when low sidelobes are required. Design and performance of an efficient matching layer between dielectric environment and free space enable utilization of such lens in frequency band about 10 %.
