This document a two-part folded waveguide with horns. For example, a waveguide includes a channel with an opening in a longitudinal direction at one end, and a sinusoidal shape that folds back and forth about a longitudinal axis that runs in the longitudinal direction through the channel. One part of the waveguide defines a surface of the channel featuring a plurality of radiation slots in the shape of a horn, which allows the two parts of the waveguide to be arranged and configured as one component. A first part of the waveguide has slots and an upper half of the walls of the channel and a second part provides a lower half of the walls of the channel and a surface of the channel opposite the slots. Using horns in combination with two parts enables ease of manufacturing a waveguide with an internal channel having a folded or sinusoidal shape.

A method of conforming a periodic array to a surface is provided. The method comprises calculating, with a spatially-variant lattice algorithm, a pair of planar gratings across the surface, wherein the planar gratings are generated via reciprocal lattice vectors and summing the pair of planar gratings. Intersections produced by summing the gratings are scanned for maxima on the surface, and a periodic array of elements is located at the maxima on the surface. A normal vector is calculated at each maximum on the surface, and each element is rotated to match the direction of the respective normal vector at each maximum on the surface. The elements are then conformed to the surface via a shrink-wrap modifier operation.

In an antenna in package structure, a plurality of supporting blocks spaced apart from each other are disposed between a first substrate and a second substrate, and an antenna cavity is formed between every two adjacent supporting blocks. Therefore, a height of the supporting block determines a height of the antenna cavity. The supporting blocks spaced apart from each other are located between the first substrate and the second substrate, and at least one of the first substrate or the second substrate adheres to the supporting blocks spaced apart from each other using an adhesive layer.

A radio frequency front end and an antenna front end may be separated from one another to maintain close proximity between a low noise amplifier and an antenna while achieving improved thermal regulation of a power amplifier.
