Abstract
An antenna device () and an antenna stack () comprising at least two antenna devices are disclosed. The antenna device comprises a leaky wave antenna structure comprising a waveguide structure () extending in a first plane along a first axis (), wherein the waveguide structure comprises two opposite end portions () along the first axis, and a first feed point and a second feed point arranged at opposite end portions of the waveguide structure. The antenna device further comprises a dispersive lens structure () having an edge extending along the waveguide structure in the first plane, the dispersive lens structure having an extension along a second axis () extending in the first plane in a second direction perpendicular to the first axis. The waveguide structure further comprises a plurality of discontinuities along an interface between the waveguide structure and the dispersive lens structure for leaking electromagnetic energy into dispersive lens structure.
