Capacity benefits of antenna coupling
@article{Termos2016CapacityBO, title={Capacity benefits of antenna coupling}, author={Abbas Termos and Bertrand M. Hochwald}, journal={2016 Information Theory and Applications Workshop (ITA)}, year={2016}, pages={1-5} }
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.
