Compact and Flexible Two-Port MIMO Antenna for UWB Wearable Applications [PDF]

EPJ Web of Conferences
This paper is about a kind of antenna called a two-port MIMO antenna. It is designed for devices that people wear, like fitness trackers or smartwatches and it works well for communication over a wide range of frequencies from 3.5 to 11 GHz. The two-port

Massive MIMO With Dual-Polarized Antennas

IEEE Transactions on Wireless Communications, 2023
This paper considers a single-cell massive MIMO (multiple-input multiple-output) system with dual-polarized antennas at both the base station and users. We study a channel model that includes the key practical aspects that arise when utilizing dual-polarization: channel cross-polar discrimination (XPD) and cross-polar correlations (XPC) at the ...
