    Abstract: Disclosed herein are various designs for dielectric waveguides, as well as methods of manufacturing such waveguides. One type of dielectric waveguides described herein includes waveguides with one or more cavities in the dielectric waveguide material. Another type of dielectric waveguides described herein includes waveguides with a conductive ridge in the dielectric waveguide material. Dielectric waveguides described herein may be dispersion reduced dielectric waveguides, compared to conventional dielectric waveguides, and may be designed to adjust the difference in the group delay between the lower frequencies and the higher frequencies of a chosen bandwidth.

    Abstract: Example antenna module includes antenna units provided over an antenna unit support, and ICs communicatively coupled to various antenna units. The ICs are arranged in two or more subsets of one or more ICs in each subset, where an individual IC belongs to only one subset, different subsets are in different layers with respect to the antenna unit support, and an average pitch of projections of all of the ICs onto a plane parallel to the antenna unit support is substantially equal to, or smaller, than an average pitch of the antenna units. When an average width of the ICs is larger than the average pitch of the antenna units, arranging the ICs in two or more subsets in different layers means that at least one of the ICs of one subset partially overlaps with at least one of the ICs of another subset.
