Abstract: An antenna package 105, which may include an RFIC 102, includes a multilayer substrate 110. The package includes an antenna array 152, which may be formed on a cover 150 of the package, antenna feed lines 112,114 and resistive transmission lines (352,354 fig. 3B). The antenna array includes active antenna elements (320 fig.3A) and dummy antenna elements (350 fig.3A) surrounding the active elements. Each active element is coupled to an antenna feed line and each dummy antenna element is coupled to a resistive transmission line. Each resistive transmission line extends through the multilayer substrate and is terminated in a same metallization layer of the multilayer package substrate. Dual polarisation may be facilitated by orthogonal feeds (201,203 fig. 2A) whilst ground planes and conductive vias (648 fig. 6B) may be used to provide isolation. A connector package (542 fig. 5) may be used instead of the package cover in order to facilitate testing of the RFIC or to connect to an external antenna array. The package may form a wireless communication package.

Abstract: An apparatus includes an antenna array package cover comprising a radiating surface, a mating surface disposed opposite the radiating surface, and an array of antenna array sub-patterns wherein each antenna array sub-pattern comprises at least one antenna element. The antenna array package also includes an array of sub-pattern interface packages mated to the mating surface of the antenna array package cover. Each sub-pattern interface package of the array of sub-pattern interface packages comprises a package carrier, a sub-pattern integrated circuit electrically and mechanically coupled to the package carrier, and a set of interface lines corresponding to the antenna elements of the antenna array sub-pattern that corresponds to the sub-pattern interface package. Methods for mounting the above apparatus into a host circuit are also disclosed herein.

Abstract: Antenna package structures are provided to implement wireless communications packages. For example, an antenna package includes multilayer package substrate, a planar antenna array, antenna feed lines, and resistive transmission lines. The planar antenna array includes an array of active antenna elements and dummy antenna elements surrounding the array of active antenna elements. Each active antenna element is coupled to a corresponding one of the antenna feed lines, and each dummy antenna element is coupled to a corresponding one of the resistive transmission lines. Each resistive transmission line extends through the multilayer package substrate and is terminated in a same metallization layer of the multilayer package substrate.
