Claim 12:
13. An antenna-in-package, comprising:
a multilayer substrate having a stack of a plurality of dielectric layers and a plurality of metal layers and comprising:
a main radiator element in a first metal layer of the plurality of metal layers;
a parasitic radiator element in a second metal layer of the plurality of metal layers, wherein the main radiator element and the parasitic radiator element are disposed in parallel and spaced by at least one of the plurality of dielectric layers;
a first feeder configured to electrically or electromagnetically couple the main radiator element;
at least one high-impedance member directly contacting the parasitic radiator element and configured to be electrically grounded; and
a grounding structure directly contacting the at least one high-impedance member and laterally surrounding the main radiator element and the parasitic radiator element; and
a chip bonded to the multilayer substrate and electrically coupled to the main radiator element and the grounding structure.
