Kraus with a host of other professors, for answers to nearly all your questions. Kraus organizes antennas by types. The dipole is the simplest complete antenna. But, the first practical antenna was patented by Marconi. He was interested in communications over the ocean, so only 1/2 of a dipole is needed. The return circuit is provided by the ocean. Sea water is nearly lossless. Marconi imagined the antenna as a capacitor plate.. Then he discovered the antenna worked about as well with just the connectng wires inplace, without the plate. As the 19th century turned into the 20th century, Marconi spanned the Atlantic with signals from his antennas. Best regards, Richard Harrison, KB5WZI A book by that title was not found on Amazon.
