On the accuracy of the transmission line model of the folded dipole

A folded dipole is basically an unbalanced transmission line which radiates as a result of its unbalanced condition. It is known that the folded dipole may be analyzed by considering its current to be composed of two distinct modes, namely, a transmission line mode and an antenna mode. The transmission line model of the folded dipole is investigated with the objectives of determining a) the accuracy of the model and b) the importance of using an equivalent radius in the model. To check the transmission line model, the method of moments is used as a standard for comparison.
