Antenna arrangements for a radio transceiver device

An antenna arrangement for a radio transceiver device, the antenna arrangement comprising:

• at least two antenna arrays, wherein at least one of the at least two antenna arrays has antenna elements of two polarizations, and wherein the antenna elements of one polarization at each of the at least two antenna arrays define a respective set of antenna elements;
• at least two baseband chains;
• a switching network comprising a number N of switches corresponding to N number of the at least two baseband chains, wherein each switch receives a signal from one of the at least two baseband chains, wherein the switching network is configured to selectively operatively connect each of the at least two baseband chains with its own set of antenna elements such that no two baseband chains are operatively connected to one and the same set of antenna elements;
• and wherein
• each of the at least one antenna array having antenna elements of two polarizations is operatively connected to the switching network via a respective hybrid connector configured to provide a signal from one of the baseband chains to antenna elements of the at least one antenna array having antenna elements of two polarizations, wherein each respective hybrid connector comprises at least one input port and at least one output port wherein the at least one input port is coupled to the switching network, receiving as input to the hybrid connector the signal from one of the at least two baseband chains.
