A Technique for MIMO Antenna Design With Flexible Element Number and Pattern Diversity
IEEE Access, 2019 This paper presents a new technique for designing multiple-input multiple-output (MIMO) antennas having pattern diversity. Massive MIMO is expected to form a part of 5G communications and will require antennas having a very large number of elements ...

Novel antenna configurations for wireless broadband vehicular communications [PDF]
, 2010 In this paper, mobile WiMAX trials are analysed to investigate the vehicular down-link performance for a number of on-car antenna configurations. The directionality and optimum polarization of the vehicular antennas are shown to improve both the range ...

Capacity Analysis and Data Detection of OvTDM-MIMO System
IEEE Access, 2023 It is well known that the channel capacity of traditional MIMO systems is positively correlated with the number of antennas, so MIMO systems usually use more antennas to meet higher system capacity requirements, which is increasingly conflicting with the

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

Near-capacity wireless transceivers and cooperative communications in the MIMO era: evolution of standards, waveform design, and future perspectives [PDF]
, 2011 Classic Shannon theory suggests that the achievable channel capacity increases logarithmically with the transmit power. By contrast, the MIMO capacity increases linearly with the number of transmit antennas, provided that the number of receive antennas ...
