Reflected wave voltage
Web15. mar 2024 · Where, V ─ & I ─ represent voltage & current of the reflected wave, and V + & I + represent voltage & current of the incident wave respectively. The above expression gives the measure of reflectance that takes place when a travelling/incident wave experiences a change in the transmission medium. There are several approaches to understanding reflections, but the relationship of reflections to the conservation laws is particularly enlightening. A simple example is a step voltage, (where is the height of the step and is the unit step function with time ), applied to one end of a lossless line, and consider what happens when the line is terminated in various ways. The step will be propagat…

WebThe Voltage Standing Wave Ratio (VSWR) is a measurement of how well an antenna is matched to a source impedance, typically 50-ohms. It is calculated by measuring the voltage wave that is headed toward the load versus the voltage wave that is reflected back from the load. A perfect match will have a VSWR of 1:1. The higher the first number, the ...
