Art, You have just mentioned a constraint on antennas that I was not aware
of. *Specifically "the ratio of capacitance to inductance must be unity".
This is new to me. Please tell me how I go about making capacitance and
inductance equal so their ratio can be unity. How do you get the Farads and
Henries to cancel out, leaving a dimensionless number.
Can you give me some real world examples?
joe
I will be happy to do so
Root L/C = 1
This means that L/C both of which are loss contributors are removed
from any formulae
Art
neither L nor C contributes any loss in any kind of circuit analysis i
have ever seen.... its always the R that converts the electrical
energy to heat to remove it from doing something useful besides
heating the room.
