Abstract
An electric emitter for vertically polarised wireless signals for a communication service with a narrow frequency bandwidth around a frequency fo with free-space wavelength λo in the gigahertz range, comprising at least one substantially horizontally oriented conductor loop arranged above a conductive base area, with an emitter infeed point for electromagnetic excitation of the loop relative to the base area. The loop is formed by a circularly closed ring conductor running in a substantially horizontal plane with a height h of less than λo/6 over the base area. Distributed over the periphery of the ring conductor are at least three vertical emitters electromagnetically coupled to the ring conductor coupling points and running to the base area, wherein at least two of the emitters are electromagnetically coupled to the base area at earth terminal points, and a vertical emitter is excited via the emitter infeed point at the lower end thereof.
