Abstract

Described and shown is a dielectric antenna (1) having a dielectric feeding section (2), a first transition section (3) comprising a dielectric rod, a dielectric emitting section (5) and, a further, second transition section (4) forming a dielectric horn, wherein the feeding section (2) can be struck with electromagnetic radiation (6), electromagnetic radiation (6) can be guided with the first transition section (3) and the second transition section (4) and the electromagnetic radiation can be emitted from the emitting section (5) as airborne waves.The object of the present invention is to provide a dielectric antenna, which is adaptable as low-loss as possible to different mounting situations, which additionally is as low-reflection as possible and, at the same time is highly bundling.The object of the above-mentioned dielectric antenna is met in that the emitting section (5) is designed as dielectric tube connecting to the second transition section (4).
