Re: NEC-LIST: Port-based Y parameters

Good day;

    An antenna is a one-port. To have two ports, as usually assumed
in a Y-parameter description, you need two antennas. With two
antennas, you could apply two voltage sources, one to each, and do the
usual textbook experiments of driving one port and measuring
(calculating) the currents in both ports to get two terms, and then
driving the other port and finding the currents to get the other two
terms, and the coupling y12=y21 should be the same.
