Polarizable antenna unit

A polarizable antenna unit, comprising

• a first printed circuit board with at least one first electrical conductor, and a
• second printed circuit board with at least one second electrical conductor,
• wherein the second printed circuit board has at least one first printed circuit board part which is configured to be partially pivotable,
• wherein the first and second printed circuit boards are arranged at a printed circuit board angle to each other,
• wherein in a first operating mode the at least one first printed circuit board part of the second printed circuit board has a first operating position with a first printed circuit board angle, in which the antenna unit has a first width,
• wherein in a second operating mode the at least one first printed circuit board part of the second printed circuit board has a second operating position with a second printed circuit board angle, in which the antenna unit has a second width,
• wherein the first printed circuit board angle is larger than the second printed circuit board angle and the second width is smaller than the first width of the antenna unit.
