Effect of antenna element properties and array orientation on performance of MIMO systems [PDF]

open access: yes, 2004
This paper presents a MIMO throughput based assessment of three candidate antenna arrays, each of which was constructed from a different type of antenna element. A model of the MIMO channel resolved in orthogonal polarization planes was employed to apply

Superbackscattering Antenna Arrays [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2015
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering cross-section, normalized to the wavelength squared, of a linear array of N isotropic scatterers whose separation tends to zero is N2(N + 1 ...

MIMO Antenna Array Design with Polynomial Factorization

open access: yesInternational Journal of Antennas and Propagation, 2013
One of the main advantages of multiple-input multiple-output (MIMO) antenna is that the degrees-of-freedom can be significantly increased by the concept of virtual antenna array, and thus the MIMO antenna array should be carefully designed to fully ...
