Radio waves: Sending a signal between two dipole antennas

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.

Radios are simply airgap transformers, with large, separated airgaps.

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?

[bennsji]

wow excellent video to explain radio wave, thanks for sharing. Bravo

❤❤❤😊😊😊😊pl🎉ease do another one for radiant energy, and power light led bulbs with rf Di pole antenna 🎉🎉

[elmultimediaschoolofartscu]

❤😊😊😊 0:20 can you add a light bulb n check radiant electricity

So antenna is a pretty bad quality transfer also?

[edmundisaac]

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??

Radio signal send past and future possible

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!
