A Folded dipole antenna is a half-wave dipole antenna with an additional parallel wire or rod connecting its two ends and folded to form a cylindrical closed shape. One pole (rod) is continuous with a length of λ/2 and the other is split at the center. During transmission, the antenna is fed at the center terminals of the two rods. Similarly, while receiving, the antenna receives the signal from these two center terminals. Folded dipole antennas usually operate in the frequency range from 3 kHz to 300 GHz and are ideal for use where an optimum power transfer and large input impedance is required.
