Abstract
We implement a cylindrical mismatched Luneburg lens at V-band, following the related theory and design rules. The lens has a relative dielectric permittivity of 2.6 at its edge, while the exterior medium is air. The implementation is done on a Printed Circuit Board, and includes the lens itself as well as Substrate-Integrated Waveguides acting as feeds and a transition from Grounded Co-planar Waveguide transmission lines to the feeds. The whole structure is fabricated as a single-piece board with standard processes. Measurements confirm that this design can produce a fan-shaped beam at multiple excitation points covering a 40 degrees angular range.
