Abstract

A dielectric antenna having an at least partially dielectric body and an electrically conductive sheath, wherein the dielectric body can be struck on a supply section with electromagnetic radiation and the electromagnetic radiation can be at least partially emitted from the dielectric body via a lens-shaped radiation section. The conductive sheath essentially surrounds the dielectric body from the supply section to the radiation section and a supply opening is provided in the conductive sheath in the area of the supply section and a radiation opening is provided in the conductive sheath in the area of the radiation section. The dielectric antenna that is easy to produce, has little interference and has a short construction as a result of the dielectric antenna having essentially the cross section of the radiation opening in the area of the supply section.
