Abstract (en)
[origin: EP2264833A2] The reflector (2) has a primary end (3) including a junction having radius (aw) adapted for coupling to an end of a waveguide (4), and a secondary end (5) having radius (Po) larger than radius of the primary end. A dielectric body is provided extending between the ends, and is limited by an inner surface and an outer surface. An outer face (1) of the reflector has a profile defined by a specific equation containing specific coordinates. The outer face of the reflector includes a relief in a form of a ring surrounding the dielectric body.
