Claim 0:
1. An electronic device comprising:
a dielectric substrate having a first set of dielectric layers with a first dielectric permittivity and having a second set of dielectric layers with a second dielectric permittivity that is greater than the first dielectric permittivity;
a ground trace on the dielectric substrate that separates the first set of dielectric layers from the second set of dielectric layers;
a phased antenna array having a first set of patch elements embedded in the second set of dielectric layers and having a second set of patch elements, wherein the first set of patch elements is configured to radiate in a first frequency band that includes frequencies greater than 10 GHz and the second set of patch elements is configured to radiate in a second frequency band that is higher than the first frequency band;
radio-frequency transmission lines having signal conductors embedded in the first set of dielectric layers, wherein the signal conductors are communicably coupled to the first and second sets of patch elements in the phased antenna array; and
fences of conductive vias in the second set of dielectric layers and coupled to the ground trace on the dielectric substrate, wherein each patch element in the first set of patch elements is separated from an adjacent patch element in the second set of patch elements by a corresponding fence of conductive vias in the fences of conductive vias.
