https://peertube.magdowski.de/videos/watch/a17cb1fe-e2c0-4ff4-818e-5eeac54ab101 In this live-streamed exercise in the "Electromagnetic Compatibility" module, we are discussing the solution of task 9 of our exericse booklet on field coupling. An electronic circuit generates an interfering power of P = 100 µW at a frequency of f = 100 MHz. At a distance r = 5 m, a broadcast antenna is located. This antenna can be described as a λ/2-dipole (half-wave dipole). How large is the maximum open-circuit voltage that is coupled into the broadcast antenna, when the disturbing circuit has an antenna gain of D = 1.5?
