Antenna geometries for improved MIMO communication

A non-transitory computer readable recording medium storing a computer program product for selecting a geometry of an antenna array in a multiple-input multiple-output (MIMO) radio communication system, the computer program product comprising program instructions which, when run on processing circuitry of a configuration device, causes the configuration device to:

• obtain a first parameter set comprising a first communication distance and a first carrier frequency, and a second parameter set comprising a second communication distance and a second carrier frequency;
• determine a first radio communication performance measure based on the first parameter set in dependence of antenna array geometry, and a second radio communication performance measure based on the second parameter set in dependence of antenna array geometry;
• and
• select the antenna array geometry based on the first radio communication performance measure and on the second radio communication performance measure;
• wherein the selecting comprises selecting the antenna array geometry to optimize a sum of the first and the second radio communication performance measures.
