MIMO antenna arrays built on metamaterial substrates

Overview

This technology is an algorithm for selecting the optimal antenna configuration in communication systems employing Multiple Input Multiple Output (MIMO), Single Input Multiple Output (SIMO), and Multiple Input Single Output (MISO) techniques. The method leverages spatial correlation, channel reciprocal condition number, delay spread, and average Signal to Noise Ratio (SNR) data to choose the most suitable antenna radiation pattern at the receiver. This approach enables capacity gains in multi-element reconfigurable antenna systems without requiring modifications to the conventional wireless communication system's data frame. The method is particularly well-suited for pattern reconfigurable antennas, as they offer advantages in terms of size and spectral efficiency.
