For One and All,
Antenna Reception Theory - Message Thread on R.R.A.A. http://groups.yahoo.com/group/Shortw...a/message/6692 Here is a Message Thread that appeared on the NewsGroup Rec.Radio.Amateur.Antenna concerning "Antenna Reception Theory" QUESTION = http://tinyurl.com/87958 " Hi, I am looking for an explanation of how an antenna receives a signal due to the E-field of an electromagnetic wave. I have looked in some books, and can understand transmission, but the books I have looked in don't explain reception. I have found an explanation of how the H-field induces a signal in a loop antenna: a changing magnetic flux will induce a current. But what about the E-field and a dipole antenna? I guess that the E-field causes electrons to move in the antenna wire, because in a solid conductor, electrons will move until the E-field inside the solid is cancelled out? I have googled but having difficulty finding a good explanation. Any pointers? Thanks & regards, Paul. " |
