A mobile communication antenna with at least one dual-polarized radiator comprises a first metal plate arrangement with a first and second side. A first printed circuit board arrangement is provided which is arranged on the second side of the first metal plate arrangement. A first free space formed between the first printed circuit board arrangement and the first metal plate arrangement. The first metal plate arrangement comprises at least one first opening through which a first feed connection of the at least one dual-polarized radiator is passed. The first feed connection is electrically connected to a first signal line on the first printed circuit board arrangement. The first feed connection of the at least one dual-polarized radiator is surrounded by an electrically conductive first shielding in a non-contacting manner.

An improved device for receiving and transmitting mobile telephony signals comprises at least 4 channels. Each of the at least 4 channels (K, K, K, K) can be controlled with a transmission signal, that is different from the other channels, which can be generated with a separate channel module (KM, KM, KM, KM) from various data streams. A controller device is provided for, via which several or all of the power amplifiers, which are connected in several or all channels (K; K, K, K, K), can be operated in-phase or phase-locked with each other, in such a way that the transmission signals (TX) amplified in the channels concerned (K; K, K, K, K) can be synchronized and interconnected. As a result, a transmission signal can be radiated with a higher transmission power.
