This paper relates to the effect of mutual coupling in multi-port antenna arrays, such as those used in MIMO radio- communication systems. Approaches of different fields of electrical engineering are used to show that the interactions between antennas may improve performance. In particular, interesting properties may be obtained when the front end of a receiver is designed as a multiple-input-port and multiple-output-port device, as opposed to multiple independent single-input-port and single-output-port devices. The case of a receiver front end implementing a MIMO series-series feedback amplifier is presented in detail.
