If the value of SWR is equal to 1, it means that the radio waves transmitted to the antenna have no reflections and all are transmitted. This is … WebReturn Loss. This bounce back reflection is called “return”. Return loss is the measure of how small the “return” or reflection/echo is. We want a small return, so a large loss on the return “echo” is good. Smaller return loss is bad, and means less energy is going into our antenna. RF engineers often measure return loss on a “dB ... newtube apkWebSep 12, 2024 · 3.14: Standing Wave Ratio. Precise matching of transmission lines to terminations is often not practical or possible. Whenever a significant mismatch exists, a standing wave (Section 3.13) is apparent. The quality of the match is commonly expressed in terms of the standing wave ratio (SWR) of this standing wave. mighty orihime fanfiction
