Abstract
An antenna assembly for emitting microwaves comprises a dielectric hollow conductor element and a support element, wherein the hollow conductor element has an electrically conductive surface along a circumferential lateral face, the hollow conductor element has an electrically non-conductive emission face, and the hollow conductor element has a coupler receptacle. The support element contains a material having a modulus of elasticity of no less than 50 GPa. The support element surrounds the hollow conductor element at least along the lateral face. The hollow conductor element is fixed in the support element. The support element has an emission opening, and the emission face aligns with the emission opening. The hollow conductor element has a permittivity of no less than 8 at 2 GHz, the hollow conductor element containing a ceramic material, in particular aluminium oxide, zirconium oxide or titanium oxide.
