1. An unattended, managed device system, comprising:
an unattended device having a plurality of items that are user-accessible at a front side of the unattended device, wherein the items are individually controlled by an on-board electronic control unit;
an antenna unit mounted atop the unattended device, the antenna unit comprising:
a housing defining a central axis, wherein the housing comprises a base member;
a first antenna providing a first radiation pattern oriented for wireless communication with a cloud-based network, the first antenna having a first radiation surface that is substantially planar and is oriented substantially orthogonal to the central axis; and
a second antenna providing a second radiation pattern that is oriented different than the first radiation pattern, wherein the second radiation pattern is oriented for wireless communication with a portable user device, and the second antenna having a second radiation surface that is substantially planar and is oriented substantially parallel with the central axis, wherein the first and second antennas are enclosed within the housing and are supported by the base member; and
a ceiling member disposed within the housing and overlaying the base member, wherein the first radiation surface is disposed atop the ceiling member, and the second radiation surface is positioned underneath the ceiling member along an axial direction parallel with the central axis.
