A novel approach to the design of MIMO arrays exploiting directive antennas is presented. It is well known that pattern orthogonality is a key issue to reach low inter-element correlation, and thus to improve channel capacity. However, in the literature the attention is often focused on reducing mutual coupling instead of optimizing the active element patterns. In this paper a MIMO array of printed...
Recent years have seen an increasing attention given to wireless Personal Area Networks (PANs), which are typically networks with small transmitter-receiver separation. The desire for high data rates has led to an interest in deploying multipleinput multiple-output (MIMO) transmission for such systems, but up until this date there exists, to the authors?? best knowledge, no MIMO channel model that...
An OFDM-MIMO testbed based on a SDR platform with very flexible antenna positioning system has been designed and presented for WLAN applications. Antenna positioning allows the proper spatial characterization of radio channel links in real scenarios where future wireless networks will be deployed. Some measurements in real indoor scenarios proving reconfigurable antennas are been carried out leading...
