Maurice - I am all in favour of full debate and welcome your contribution. The problem is that antennas cannot be "isolated" if they are close together, if they are antennas they couple. That is what antennas do - they have no other useful function. So if someone has two structures that don't couple, they are by definition not effective antennas. . . . On the near field argument, I would stick my neck out and say there is no solution of Maxwell's equations that allows a negligible near field distribution near a source of energy. I am ready to be proved wrong but so far nobody has come up with a reasoned quantitative argument . . . The 1992 paper by Martin Smith looks all right to me and several people have agreed its accuracy, and as far as I remember it was purely theoretical, so it is immaterial whether the phases were zero and 90 degres, or plus and minus 45 degrees . . . . Best regards, Alan
