Question

Difference between half wave dipole and folded dipole

Answer 1

Answer:wave dipole :

In radio and telecommunications a dipole antenna or doublet is the simplest and most widely used class of antenna.

folded dipole :

A folded dipole is an antenna, with two conductors connected on both sides, and folded to form a cylindrical closed shape, to which feed is given at the center. The length of the dipole is half of the wavelength. Hence, it is called as half wave folded dipole antenna.

Explanation:

Answer 2

Let us know the differences between half-wave dipole and folded dipole-

1. The actual length of the net wire, which is utilized as a dipole, is equal to half of the wavelength i.e., l = λ/2. This type of antenna is known as a half-wave dipole antenna.

2. A folded dipole is a type of antenna consisting of two conductors connected on both sides and further folded to create a cylindrical type closed shape, to which feed is provided at the center.

3. Suppose, for example, only makes sense to compare a half-wave dipole (that is used most commonly) to a half-wave folded dipole and the only distinction in electrical features is that the dipole has approximately 73 ohms impedance whereas the folded dipole consists of 4 times that impedance, or approximately 300 ohms.
