Abstract
Many wireless communication standards (4G LTE, 5G NR, Wi-Fi, etc.) can leverage multiple antennas within a device through multiple-input multiple-output (MIMO) communication protocols. Antenna tuners are often used to tune the individual antennas for various transmission and reception characteristics. Traditional means of tuning the antennas, however, do not account for coupling between the antennas. Often, MIMO antennas are packaged within proximity of each other due to tight packaging constraints in modern electronic devices. In these types of coupled MIMO systems, maximum throughput is achieved when the coupling between the antennas is accounted for, even though a single antenna may not be optimized. By utilizing a signal-to-noise (SNR) matrix that includes coupling terms between the antennas to determine tuning parameters, the MIMO antennas can be dynamically optimized as a system rather than individual tunable antennas.
