What is advantage of folded dipole?

Folded dipole advantages

Wide bandwidth: The folded dipole antenna has a flatter frequency response – this enables it to be used over a wider bandwidth with many transmissions utilising a variety of different selectable channels, e.g. television and broadcast radio, a wide bandwidth antenna is needed.

What is folded antenna?

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.

What is the input impedence of a folded dipole antenna?

At resonance, the impedance of a half-wave dipole antenna is approximately 70 Ohms, so that the input impedance for a half-wave folded dipole antenna is roughly 280 Ohms.

What is the main difference between half wave and folded dipole?

Explanation: As an example, only makes sense to compare a 1/2 wave dipole (most commonly use) to a half-wave folded dipole and the only differences in electrical characteristics are that the dipole has roughly 73 ohms impedance and the folded dipole has 4 times that impedance or roughly 300 ohms (Ken was right).

Is a folded dipole antenna directional?

The directivity of Folded dipole Antenna is bi-directional. The input impedance is higher.

What is true about folded dipole?

Explanation: The impedance of folded dipole is four times the impedance of the half dipole. So its impedance is higher than the half dipole. Since folded dipole is a balanced antenna we use a balanced feeder so Balun is used.
