(yet another) transmission line question
More for the fun of pondering it than for any immediate practical
reason... If I make a balanced two-wire transmission line from round wires, and I'm constrained to have the wire center-to-center spacing some particular value (say one inch, or five centimeters, or whatever), what wire diameter should I use to get the lowest matched-line loss? What impedance line does that give (assuming air dielectric)? Clearly for a given wire diameter, the wider the spacing the lower the loss up to the point where radiation plus dielectric loss becomes significant, but I can imagine situations where you want to limit the wire spacing and get low loss. Cheers, Tom |
