Simulation of a folded dipole using curved wires at the dipole ends. The curved part is modeled exactly using conformal segments. AN-SOF applies the Conformal Method of Moments (CMoM) > instead of the traditional MoM, which uses a straight wire approximation to curved wires.
The standard donut shaped radiation pattern is obtained with a small distortion. Folded dipoles are used to increase the radiation resistance of a standard half-wave dipole (about 75 Ohm). The input impedance of the folded dipole shows a real part near to 300 Ohm.
