Transmission Line & wave guide
Transmission line theory
The two-wire line acts like a long capacitor . capacitive reactance changed when the frequency applied to it is changed
Long conductors have a magnetic field about them ,when electrical energy is being passed through them, they also exhibit the properties of inductance.
Line Losses
Copper Loss
Dielectric Loss
Radiation Loss
Induction Loss
Conclusion
It can be concluded that the simplest transmission line with a right angle bend possesses the most effective signal transmission than any other types of bends in terms of radiation loss.
Improperly connected joints or damaged inner surfaces can decrease the efficiency of a system to the point that it will not work at all. Therefore, you must take great care when working with Antennas & wave guides
