A Complete MIMO System Built on a Single RF Communication Ends

It is well known that Multiple Input-Multiple Output systems enhance significantly the spectral efficiency of wireless communication systems. However, their remarkable hardware and computational burden hinders the wide deployment of such architectures in modern systems. In this paper, we present an alternative MIMO architecture built on parasitic antenna structures with small inter-element distance. We show that exploiting appropriately the beamforming capabilities of such antennas, a cost efficient MIMO transceiver architecture emerges, with low implementation complexity. Our proposal is evaluated against the corresponding conventional MIMO systems in terms of bit error rate and capacity, and the results show a satisfactory performance.
