Claim of US Patent No. 10,219,389

1. An electronic device comprising:a computing environment comprising active components attached to and functionally interconnected on more than one layer of a multilayer printed circuit board (PCB), where a planar surface of each layer of the multilayer PCB defines a horizontal plane;
a communication module in communication with the active components of the computing environment, the communication module transceiving in a millimeter wave (mmWave) band via an input/output component;
at least one ground plane formed on at least a portion of a planar surface of the multilayer PCB, the input/output component comprising a conductive component attached to the multilayer PCB;
two or more metal components that are physically attached to the multilayer PCB and electrically coupled to the at least one ground plane;
a monopole antenna electrically connected to the input/output component, positioned vertically through one or more layers of the multilayer PCB, positioned proximate to one lateral side of the multilayer PCB, and aligned between two adjacent ones of the two or more metal components; and
one or more vertical stubs formed through the multilayer PCB, vertically aligned with the monopole antenna, and spaced to a side of the monopole antenna opposite to the one lateral side of the multilayer PCB, each vertical stub electrically grounded to the ground plane;
wherein the two adjacent ones of the two or more metal components and the one or more vertical stubs shape beam directivity of the monopole antenna toward the one lateral side of the multilayer PCB.
