Mobile radio antenna for connection to at least one mobile base station

A mobile radio antenna for connection to at least one mobile base station, having the following characteristics:

• there are provided a plurality of radiating elements and a carrier assembly;
• the plurality of radiating elements are arranged on a first side of the carrier assembly and are adapted to sending and receiving mobile radio signals in at least a first mobile radio band;
• there is provided an antenna array module, arranged on a second side of the carrier assembly, the antenna array module comprising at least a first housing module;
• the first housing module comprises a first receiving space, which is bounded by side walls and a housing bottom, and a second receiving space, which is bounded by side walls and a housing bottom;
• the first and second receiving space are separated from each other by at least one partition;
• there is provided at least a first phase shifter arrangement, situated in the first receiving space, comprising a common terminal and a plurality of antenna-side terminals, wherein each antenna-side terminal of the first phase shifter arrangement is electrically connected directly or indirectly to a first terminal of at least one radiating element;
• there is provided at least a first duplex filter assembly, situated in the second receiving space, wherein the first duplex filter assembly comprises a common terminal and a first TX terminal and a first RX terminal;
• the at least one partition comprises a first opening, wherein the common terminal of the first duplex filter assembly is electrically or electromagnetically connected to the common terminal of the first phase shifter arrangement through the first opening;
• and
• the first duplex filter assembly has a damping/transmission function such that:
• c) transmit signals of a transmission band in the at least one first mobile radio band are passed through from the TX terminal to the common terminal;
• and
• d) receive signals of a reception band in the at least one first mobile radio band are passed through from the common terminal to the RX terminal;
• and
• c) transmit signals in the at least one first mobile radio band are subjected to a blocking attenuation from the TX terminal to the RX terminal;
• and
• d) receive signals in the at least one first mobile radio band are subjected to a blocking attenuation from the common terminal to the TX terminal, wherein
• the housing module comprises a first and a second housing half;
• the first housing half comprises a housing bottom and side walls, by which the first receiving space is enclosed;
• the second housing half comprises a housing bottom and side walls, by which the second receiving space is enclosed;
• the first and the second housing half are placed one on the other, so that the end faces of the side walls of the first and the second housing half are oriented toward each other;
• the first phase shifter arrangement comprises a common circuit board assembly, wherein a first side of the common circuit board assembly is covered predominantly or entirely with a metal layer;
• the common circuit board assembly closes off the second receiving space, the first side pointing in the direction of the second receiving space;
• and
• the at least one partition is formed by the metal layer of the second side of the common circuit board assembly, the first opening passing through the common circuit board assembly.
