Can someone explain how a transmission line starts radiating as the separation between the center conductor and ground plane becomes greater and greater. Assume you out start with a wire over an infinite copper ground plane that forms a 50 ohm Zo transmission line. Then increase the distance between the wire and the ground plane until the wire becomes an end fed antenna. What happens to cause radiation to begin? Electrons shed excess energy by emitting photons. If those photons are absorbed by electrons, they don't radiate. If they are not absorbed, they radiate (at the speed of light). This is one area where quantum electrodynamics is actually easier to understand, from a conceptual standpoint, than Maxwell's equations. -- 73, Cecil http://www.qsl.net/w5dxp -----= Posted via Newsfeeds.Com, Uncensored Usenet News =----- http://www.newsfeeds.com - The #1 Newsgroup Service in the World! -----== Over 100,000 Newsgroups - 19 Different Servers! =----- |
