Aerial for the reception of circularly polarized satellite radio signals comprising at least one substantially horizontally oriented conductor loop arranged over a conductive base surface, having an assembly for electromagnetic excitation of the conductor loop connected to an aerial connection. The conductor loop is designed as a loop emitter by a polygonal or circularly closed loop extending in a horizontal plane of height h above the conductive base surface. The loop emitter forms a resonant structure and is electrically excited by the electromagnetic exciter in such a way that on the loop the current distribution of a travelling line wave occurs in one direction of rotation only, of which the phase difference over one revolution is M*2π, where M is an integer and has at least a value of M=2. To facilitate the vertically oriented fractions of the electromagnetic field, there is at least one emitter which extends vertically at the circumference of the loop emitter and to the conductive base surface and which is electromagnetically coupled to both the loop emitter and the electrically conductive base surface. The height h is lower than ⅕ of the free-space wavelength λ.
