Abstract: A waveguide antenna system, includes: an electromagnetic, EM, transition portion having a transition region having a signal feed interface and an open waveguide section, the EM transition portion configured to couple EM energy from the signal feed interface to a guided waveguide mode of EM energy to the open waveguide section via the transition region; and a leaky waveguide antenna portion configured and disposed to radiate electromagnetic energy received from the open waveguide section; wherein the EM transition portion is electromagnetically coupled to the leaky waveguide antenna portion, the EM transition portion being configured to support a transfer of electromagnetic energy from a signal feed structure to the leaky waveguide antenna portion.

Abstract: A dielectric lens, includes: a three-dimensional, 3D, body of dielectric material having a spatially varying dielectric constant, Dk; the 3D body having at least three regions R(i) with local maxima of dielectric constant values Dk(i) relative to surrounding regions of respective ones of the at least three regions R(i), locations of the at least three regions R(i) being defined by local coordinates of: azimuth angle(i), zenith angle(i), and radial distance(i), relative to a particular common point of origin associated with the 3D body, where (i) is an index that ranges from 1 to at least 3; wherein the spatially varying Dk of the 3D body is configured to vary as a function of the zenith angle between a first region R(1) and a second region R(2) at a given azimuth angle and a given radial distance.
