Radio waves: Sending a signal between two dipole antennas
Вставка
- Опубліковано 25 сер 2024
- A transmitting antenna, consisting of two aluminium bars, is connected to a waveform generator, which supplies the antenna with an alternating current. Due to that, particles within the bars start to oscillate. Changing electric and magnetic fields are generated, detach from the antenna, and spread. These radio waves impinge on the receiving antenna and get displayed on the oscilloscope.
This is an experiment from the first-semester lecture "Electricity and Magnetism" given by Christian Bettstetter in the bachelor program "Informationstechnik" at the University of Klagenfurt, Austria.

Brilliant
Love it
wow excellent video to explain radio wave, thanks for sharing. Bravo .....
can you explain more in detail on how the antenna are connected to the function generator/oscilloscope? are each bar connected to negative and positive?
Right! And does the transmitting antenna contain some kind of RF power amplifier? Are the two antennas a special piece of lab equipment or just aluminum rods on a stand? This is a good video but a little more set-up information would make it great.
why is she able to transmit 8mhz signal through an antenna less than 30m given that λ=cf will give us a wavelength of 38m approx??
So antenna is a pretty bad quality transfer also?
Super 😊
pretty cool
Thanks
I like it!
Radio signal send past and future possible
how high can we get the frequencies?
rare video that very close to how really antenna work...all the videos and google dont explain right how antenna work...explain it completly wrong.
A missed opportunity to convey anything of import. In fact, a complete waste of two minutes for anyone who knows even the basic basics!
