Antennas can couple if they are placed near each other, such as on portable wireless devices. Such coupling is often viewed as a nuisance that is a detriment to system performance. We show how coupling, if exploited properly, can lead to higher achievable data rates than an equivalent uncoupled system. Our conclusions build on some recent results on the bandwidth of coupled radiofrequency systems.

Diversity Limits of Compact Broadband Multi-Antenna Systems

It will be shown that mutual coupling creates eigen-modes (virtual antennas) with diverse frequency responses, using the standard matching techniques, and how common communications techniques such as Diversity-OFDM would need to be optimized in order to compensate for these effects.

Fundamental capacity limits on compact MIMO-OFDM systems
