14. A household microwave appliance, comprising a rotary antenna including a plurality of wings rotatable about a common axis of rotation, with a relative angle between at least two of the plurality of wings configured to be adjustable about the axis of rotation,
wherein the at least two wings are rotatable by wing axes arranged coaxially with respect to one another, and
the wing axes have each an electrically conductive section, which is connected to the respective one of the at least two wings, said electrically conductive section projecting into a part of a microwave guide, wherein the at least two wing axes define an outer wing axis and an inner wing axis, with the electrically conductive section of the outer wing axis being embodied as a lateral shield for the electrically conductive section of the inner wing axis, and with the electrically conductive section of the inner wing axis within the microwave guide projecting beyond the electrically conductive section of the outer wing axis.
