1. An antenna package, comprising:
a multilayer package substrate comprising a plurality of laminated layers, each laminated layer comprising a patterned metallization layer formed on an insulating layer;
wherein the multilayer package further comprises:
a planar antenna array which comprises an array of active antenna elements and a plurality of dummy antenna elements disposed around an entire outer perimeter of the array of active antenna elements;
a plurality of antenna feed lines, wherein each active antenna element is coupled to a corresponding one of the antenna feed lines; and
a plurality of resistive transmission lines, wherein each dummy antenna element is coupled to a corresponding one of the resistive transmission lines;
wherein each resistive transmission line extends through the multilayer package substrate and is grounded in a same metallization layer of the multilayer package substrate to thereby terminate radiation incident on the dummy antenna elements.
