    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: An integrated circuit (IC) package may be fabricated having an interposer, one or more microfluidic channels through the interposer, a first IC chip attached to a first side of the interposer, and a second IC chip attached to a second side of the interposer, where the first side of the interposer includes first bond pads coupled to first bond pads of the first IC chip, and the second side of the interposer includes second bond pads coupled to first bond pads of the second IC chip. In an embodiment of the present description, a liquid cooled three-dimensional IC (3DIC) package may be formed with the IC package, where at least two IC devices may be stacked with a liquid cooled interposer. In a further embodiment, the liquid cooled 3DIC package may be electrically attached to an electronic board. Other embodiments are disclosed and claimed.

    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.
