An electronic device includes a housing having a plurality of panels
connected together to define a closed geometric shape having one or more
corners. An electrically conductive layer is carried by the housing to
define a first dipole element, and a second dipole element is carried by
housing adjacent one corner thereof. Circuitry comprising at least one
active electronic component, such as sensor and/or a battery, is mounted
within the housing, and an antenna feed is connected between the
circuitry and the first and second dipole elements.
