Web10 de dez. de 2012 · The charges keep moving around the hole as the antenna's field changes, and you end up with moving charges (current) held apart by the hole (voltage), just as there would be in an antenna. Consequently, some of the energy is re-radiated. In fact, if the hole is the right size, it can be just as efficient as an antenna. WebThe words antenna and aerial are used interchangeably.
