The antenna (10) has a set of aerial elements placed around a longitudinal axis (A) of the antenna, and a support structure for the aerial elements. Each aerial element comprises a monopole that is arranged parallel to the axis. The support structure forms a reflector (100) for reflecting electromagnetic waves emitted by the monopole. The support structure comprises a base (34), an intermediate part and a cap (38). The base has an upper part (42) with an external wall (46) and an internal wall (47), where the external wall is designed planar and arranged transverse to the axis. |
