Abstract (en)
[origin: EP3843216A1] A low-profile antenna in package relates to the semiconductor field, and in particular, to the antenna in package field. The antenna in package includes a substrate, and a radio frequency processing chip electrically connected to the substrate. A feed path, radiation patches, and overlay arrays corresponding to the radiation patches are disposed in the substrate. The radio frequency processing chip feeds power to the radiation patches through the feed path, and resonates the overlay arrays. A reflection phase of each of the overlay arrays within an operating band is less than 90°, and there is a zero reflection phase region within the operating band. The overlay arrays may be metamaterial overlays. The antenna in package may be applied to a terminal device, especially a smartphone, to reduce a profile height of the antenna in package, so that the terminal device is more miniaturized.
