The paper presents an antenna system with combined
full-duplex and 2-order multiple-input-multiple-output
(MIMO) functionalities, i.e., a system capable of spatially multiplexing
and spatially demultiplexing 2 datastreams in the same
frequency and in the same time. By exploiting symmetries
in the construct and the feed, simple corrective beamforming
weights can be applied at the transmitter (Tx) ports in order
to selectively cancel the Tx signal at the receiver (Rx) ports,
thus guaranteeing a large amount of isolation necessary for fullduplex
(i.e., simultaneous and in-band Tx and Rx) operation. On
the other hand, the 2 MIMO ports (either at the Tx or at the
Rx) are sufficiently decoupled thanks to polarization diversity.
The proposed antenna system exhibits a remarkable level of fullduplex
isolation over a wide bandwidth while maintaining low
coupling between its MIMO ports and can serve as a concrete
implementation of an antenna system equipped with both MIMO
as well as full-duplex capabilities.
