WebbIn slow-wave antenna, the guided wave is a slow wave, meaning a wave that propagates with a phase velocity vph that is less than the speed of light in free space. howe throwout bearing installationIn radio and telecommunication, a traveling-wave antenna is a class of antenna that uses a traveling wave on a guiding structure as the main radiating mechanism. Its distinguishing feature is that the radio-frequency current that generates the radio waves travels through the antenna in one direction. This is in contrast to a resonant antenna, such as the monopole or dipole, in which the antenna acts as a resonator, with radio currents traveling in both directions, bouncing back and f… hideaway zillertalWebbThe slow wave radiation fields of a slotted line antenna are calculated inside the antenna region.
