The invention relates to a modular antenna system and a method for signal processing using the said modular antenna system. The object of the invention is to overcome the missing scalability of conventional antenna arrays and an improvement of the overall antenna array performance as well as a possibility for individually replacing defect or not reliably operating radio-units or radio-subunits in modular antenna array systems and providing a calibration procedure which can be adapted to a scalable antenna array. This is solved by a modular antenna system comprising a base station, at least one radio-unit comprising at least two radio-subunits, each radio-subunit comprising a radio-module and an antenna-module whereas said radio-module comprising a digital signal-processing unit, at least a transceiver, a front-end and a power amplifier, wherein the at least two radio-subunits provide an identical architecture and are modularly connected together via a connector interface and each radio-subunit has an own IQ-input and an own IQ-output.

Modular antenna system

The utility model discloses an active antenna module and an active antenna and belongs to the field of communication. The active antenna module comprises a casing and an antenna device arranged in the casing. Hoisting holes are arranged on the casing, and grabbing structure positions are arranged on the casing. The active antenna module is convenient to install in the sky due to the fact that the hoisting holes and the grabbing structure positions are arranged on the casing, and maintainers can hold the module in maintenance. The active antenna module and the active antenna have the advantages of being simple in structure, convenient to operate, safe and reliable and ensuring that the active antenna module is safe to install, maintain and install and high in efficiency.
