Put Your Antenna Under a Microscope Now, admittedly the average antenna doesn't contain any pithballs. But it does contain hordes of minute, lightweight, electrically charged particles called electrons. Many of these are so-called free electrons that have broken loose from their parent copper or aluminum atoms and are able to

WebFeb 1, 2003 · One of the least understood phenomena in electrical engineering is the idea that electric and magnetic fields appear to leave a radio transmitting antenna to form … The antenna's power gain (or simply "gain") also takes into account the antenna's efficiency, and is often the primary figure of merit. Antennas are characterized by a number of performance measures which a user would be concerned with in selecting or designing an antenna for a particular application. A plot of the directional characteristics in the space surrounding the antenna is its radiation … WebJan 4, 2007 · 40. People don't really think of radio-frequency radiation in terms of discrete particles -- they typically use the wave model instead, as it's much easier to use. An efficient antenna produces a large-amplitude EM wave for a given feed power, and produces little heat. An inefficient antenna produces a small-amplitude EM wave for the same feed ... sims 4 school mod 2021
