1. An antenna assembly for emitting microwaves, comprising:
a dielectric hollow conductor element; and
a support element,
wherein the dielectric hollow conductor element has an electrically-conductive surface at least along a circumferential lateral surface,
wherein the dielectric hollow conductor element has an electrically non-conductive emission surface,
wherein the dielectric hollow conductor element has a coupler receptacle, wherein the coupler receptacle includes a bore through which a pin-shaped coupler extends which is terminated with a capacitively-acting element,
wherein the support element has a material having a modulus of elasticity of not less than 50 GPa,
wherein the support element surrounds the dielectric hollow conductor element at least along the lateral surface,
wherein the dielectric hollow conductor element is fixed in the support element, and
wherein the support element has an emission opening and the emission surface of the dielectric hollow conductor element is aligned with the emission opening.
