Abstract:
1. Dielectric antenna, comprising: an at least partially dielectric body and an electrically conductive sheath, wherein the at least partially dielectric body has a supply section for receiving electromagnetic radiation and a lens-shaped radiation section from which the electromagnetic radiation is at least partially emitting, wherein the conductive sheath essentially surrounds the at least partially dielectric body from the supply section to the radiation section, wherein the conductive sheath has a cylindrical sidewall, wherein a supply opening is provided in the conductive sheath in an area of the supply section; wherein a radiation opening is provided in the conductive sheath in an area of the radiation section; wherein a cross-section of the supply section is the same as a cross-section of the radiation opening, and the cross-section of the radiation opening is the same as a cross-section of the cylindrical sidewall, extending perpendicular to a main radiation direction, wherein the at least partially dielectric body comprises a dielectric material in a boundary section adjacent to the conductive sheath that has a lower permittivity than other sections of the dielectric body.
