Abstract
The performance of an antenna cancellation technique for a multiple-input–
multiple-output (MIMO) full-duplex system that is based on
null-steering beamforming and antenna polarization diversity is investigated.
A practical implementation of a symmetric antenna topology
comprising three dual-polarized patch antennas operating at
2.4 GHz is described. The measurement results show an average of
60 dB self-interference cancellation over 200 MHz bandwidth.
Moreover, a decoupling level of up to 22 dB is achieved for MIMO
multiplexing using antenna polarization diversity. The performance
evaluation of the proposed technique was performed by simulation
and measurement and the results have good agreement.
