Antenna modules employing a package substrate with a vertically-integrated patch antenna(s), and related fabrication methods. The antenna module includes a radio-frequency (RF) IC (RFIC) package that includes one or more RFICs for supporting RF communications and a package substrate that includes one or more metallization layers with formed metal interconnects for routing of signals between the RFICs and an antenna(s) in the package substrate. The package substrate includes one or more patch antennas that are planar-shaped and vertically integrated in a plurality of metallization layers in the package substrate, behaving electromagnetically as a patch antenna. In this manner, the patch antenna(s) can be formed as a vertically-integrated structure in the package substrate with fabrication methods used for fabricating metal interconnects and vias (e.g., a micro via fabrication process) in package substrates.

Multi-directional antenna modules employing a surface-mount antenna(s) to support antenna pattern mufti-directionality, and related fabrication methods. The antenna module includes a radio-frequency (RF) IC (RFIC) package that includes one or more RFICs for supporting RF communications and a package substrate that includes one or more metallization layers with formed metal interconnects for routing of signals between the RFICs and multiple antennas in the package substrate. To provide multi-directionality in antenna radiation patterns, a first antenna is provided that is coupled to the package substrate and oriented in a first plane, and a second antenna is provided that coupled to the package substrate and oriented in a second plane orthogonal to the first plane. In an example, the second antenna is packaged in an antenna package that includes external metal pads that when surface mounted to the package substrate, cause the second antenna to oriented in the second plane.
