On the Duality between MIMO Systems with Distributed Antennas and MIMO Systems with Colocated Antennas [PDF]
EURASIP Journal on Advances in Signal Processing, 2007 Multiple-input multiple-output (MIMO) systems are known to offer huge advantages over single-antenna systems, both with regard to capacity and error performance. Usually, quite restrictive assumptions are made in the literature on MIMO systems concerning

Wireless Personal Communications, 2023 In this work, two types of Vivaldi MIMO antenna are designed and fabricated. The first one is a two ports band-reject Vivaldi MIMO antenna. The second one is a two ports band-reject Vivaldi MIMO antenna with a dielectric lens. Measurements show that the experimental working band of both is 3 to 12 GHz with isolation between ports higher than 25 dB ...
