Abstract

A mobile communications antenna comprises at least one antenna housing with a housing front side, a housing rear side, a first lateral housing side and a second lateral housing side opposite to the first. In the antenna housing, there are multiple radiating elements or pairs of radiating elements. The antenna further includes at least two amplifier modules, wherein each amplifier module comprises a first connection port and a second connection port and the amplifier modules are mounted on the exterior of the antenna housing. The connection ports are connected to corresponding first and second connection contact devices via plug-in connections. At least one signal processing and/or control unit is disposed in a housing, which is separate from the amplifier modules, in or on the antenna housing of the mobile communications antenna. The at least one signal processing and/or control unit comprises at least one digital interface to a baseband unit or to the mobile communication network and interfaces to the separate amplifier modules.
