The Physics of Basic Antenna Theory and Design :: physics

Long ago there lived a race of cat people who had untold the same problems with antennas that we earth fork over today bad reception during the last few seconds of a game, continual snow during their favorite part of their favorite movie, and a severe wish of the magic position that one is required to hold when covered in tin foil and grasping the antenna. Unfortunately for them, they did non have this web rogue to reference and therefore they died. This left an opening for humans. Initially, humans could only communicate verbally over short distances, yelling distance that is, rousing in them a desire for long distance communication (very different from a long distance relationship, do not make the two confused, opposite than this site will make absolutely no sense). Okay, so I made that part about the cats up, but seriously, if anyone knows how to get good reception with a younger brother covered in tin foil, let me know......not that I have done it, mind you, I am just w ondering. Now, on with the show.The stolon antenna experiments were conducted by Joseph Henry in 1842 at Princeton University. Henry was successful at throwing a spark, when he observed that magnetic needles were magnetized by a current bring on in a circuit several floors up. In 1885, Thomas Edison patented a communication system the used a shell of vertical antenna. wherefore came James Clerk Maxwell, who in 1864, presented his surmisal on electromagnetism to the Royal Society, providing the theoretical foundation for antennas. With this discovery, many other scientists began to explore this bracing frontier and the date of the radio began.Just so you do not end up like this guy, I am going to explain a few hurt so the technical discussion is a little easier to follow. (Note do not actually try to open a window in such a manner, you will most likely throw your shoulder out because mice have relatively low mass and it takes a heck of an arm to get them up to window crackin g speed, aka ludicrous speed for you Space Balls fans). The terminology is as followsTechnical Stuff Here is the information that goes a little deeper into the theory of how an antenna works. Although this is not a very intellectually intense site, I will warn those viewers on a lunch break or perhaps surfboarding the net while between projects, that there are some concepts on this page that use what some people call math, and other supposedly chief(prenominal) scientific information.The Physics of Basic Antenna Theory and Design physicsLong ago there lived a race of cat people who had much the same problems with antennas that we humans have today bad reception during the last few seconds of a game, continual snow during their favorite part of their favorite movie, and a severe lack of the magic position that one is required to hold when covered in tin foil and grasping the antenna.
