ABSTRACT:
An arrangement for feeding a centrally focused reflector antenna includes a waveguide (1), a dielectric field transformer (2) arranged on the waveguide (1) and a mounting platform (3) for a series of modules (8) which is embodied on one end of the waveguide (1). The waveguide (1) is provided with an arrangement for receiving the dielectric field transformer (2) which partially protrudes into the waveguide (1). Preferably, a dielectric support (9) may be provided in the vicinity of the dielectric field transformer (2). The middle of the support has a circular bore (12) whose diameter corresponds to the diameter of the dielectric field transformer (2). The centrally focused reflector antenna can be excited in the focal point thereof in a field-optimum broadband manner.
