A related concept is reflectionless impedance matching. In radio frequency transmission lines, and other electronics, there is often a requirement to match the source impedance (at the transmitter) to the load impedance (such as an antenna) to avoid reflections in the transmission line that could overload or damage the transmitter. Witryna12 kwi 2024 · It is found that the axial ratio is less than 3 dB in a frequency range of 0.93 f 0 (≡ f L) to 1.44 f 0 (≡ f U), corresponding to a bandwidth of 43% [= 100 × (f U − f L) / {(f L + f U) / 2}].
