This letter experimentally demonstrated the performance improvement of orbital-angular-
momentum (OAM) based 2 * 2 MIMO communication by using the diversity of different OAM
modes. The OAM antenna we used is an eight-arm Archimedean spiral antenna (ASA)
capable of generating multiple high-quality OAM vortex waves individually or two types of
two-mode mixed vortex waves simultaneously. Both of the two cases are investigated for
MIMO communication by evaluating the throughput performance. For MIMO with two OAM …

This letter experimentally demonstrated the performance improvement of orbital-angular-momentum (OAM) based 2 2 MIMO communication by using the diversity of different OAM modes. The OAM antenna we used is an eight-arm Archimedean spiral antenna (ASA) capable of generating multiple high-quality OAM vortex waves individually or two types of two-mode mixed vortex waves simultaneously. Both of the two cases are investigated for MIMO communication by evaluating the throughput performance. For MIMO with two OAM modes (generated by two ASAs separately), the throughput improves upon traditional MIMO by up to 30.50%, while for MIMO with two-mode mixed vortex waves (generated by one ASA), 6.59% throughput improvement is obtained.
