= Return loss
{wiki=Return_loss}
Return loss is a measure used in telecommunications and electronics to quantify the amount of signal reflected back from a device or transmission line, such as an antenna, cable, or connector. It indicates how well the input impedance of a device matches the characteristic impedance of the transmission medium. Return loss is expressed in decibels (dB) and is defined as the ratio of the power of the reflected signal to the power of the incident signal.
