where RL(dB) is the return loss in dB, P i is the incident power and P r is the reflected power. Return loss is related to both standing wave ratio (SWR) and reflection coefficient (Γ). Increasing return loss corresponds to lower SWR. Return loss is a measure of how well devices or lines are matched. A match is good if the return loss is high.
Examples of estimated bandwidth of different antennas according to the schedule VSWR and return loss by the help of the ANSYS HFSS [1]. Ansys HFSS (high-frequency structure simulator) is a commercial finite element method solver for electromagnetic (EM) structures from Ansys.
Voltage standing wave ratio (VSWR) (pronounced "vizwar" [1] [2]) is the ratio of maximum to minimum voltage on a transmission line . For example, a VSWR of 1.2 means a peak voltage 1.2 times the minimum voltage along that line, if the line is at least one half wavelength long.
The voltage standing wave ratio (VSWR) at a port, represented by the lower case 's', is a similar measure of port match to return loss but is a scalar linear quantity, the ratio of the standing wave maximum voltage to the standing wave minimum voltage.
Ford said it would cut around 14% of its European workforce on Wednesday, blaming losses in recent years due to weak electric vehicle demand, poor government support for the EV shift and ...
Perhaps over 30% of all antenna papers submitted to the Transactions in the past twelve months have used return loss incorrectly. The reason for this is uncertain. To remind everyone of the correct terminology, I review the definition of return loss, briefly outline the history of the term, and give some examples of current misuse. </quote>
As it does every year, NORAD, the North American Aerospace Command, tracked Santa on his trip around the world on Christmas Eve so children and families could see where he was.
After Friday's loss, Louisville coach Pat Kelsey said the initial concern for his players was to recover sufficiently for Tuesday. "They played three rock fights (in the Bahamas), as I like to ...
