![]() "Paul Taylor" wrote in message news ![]() 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. =================================== It is impossible for an E-field to exist without an H-field. Therefore, antennas of all sorts receive signals in the same way as a simple loop. Calculations can begin using either the E-field or the H-field but they both give the same answer. ---- Reg. |
