1. A wireless device comprising:
a support structure;
a first radio that operates according to a first radio function;
a second radio that operates according to a second radio function that is different than the first radio function;
a first phased array antenna coupled to the first radio, the first phased array antenna comprising a first plurality of antenna elements disposed on a surface of the support structure, the first plurality of antenna elements being organized as a first set of concentric patterns of antenna elements, the first set of concentric patterns of antenna elements defining a first set of annuluses in which there are none of the first plurality of antenna elements, each annulus of the first set of annuluses being located between two concentric patterns of the first set of concentric patterns; and
a second phased array antenna coupled to the second radio, the second phased array antenna comprising a second plurality of antenna elements disposed on the surface of the support structure, the second plurality of antenna elements being organized as a second set of concentric patterns of antenna elements, the second set of concentric patterns of antenna elements defining a second set of annuluses in which there are none of the second plurality of antenna elements, each annulus of the second set of annuluses being located between two concentric patterns of the second set of concentric patterns, wherein the second set of concentric patterns of antenna elements of the second phased array antenna are located in the first set of annuluses of the first phased array antenna, and wherein a subset of the first set of concentric patterns of the first phased array antenna are located in the second set of annuluses of the second phased array antenna.
