Abstract
The benefits of exploiting a triangular-lattice arrays employed in massive MIMO systems is addressed. Performance comparison with respect to a square lattice planar array has been carried out within 5G NR n257 and n258 frequency band. Particular attention is paid to illustrate the effect of the array lattice at the system level by evaluating significant figure of merits such as the Sum Spectral Efficiency (SSE), Signal to Interference Ratio (SIR) and array gain. The observed advantages offered by the triangular arrangement of antenna elements in terms of improved gain and SSE as well as the thermal aspect make it appealing for massive MIMO 5G applications.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
