What Is Folded Dipole Antenna?

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. ... Hence, it is called as half wave folded dipole antenna. The directivity of Folded dipole Antenna is bi-directional. The input impedance is higher.

What are the advantages of folded dipole antenna?

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.

Why is a dipole folded?

Radiation Pattern

Half-wave folded dipole antennas are used where optimum power transfer is needed and where large impedances are needed. This folded dipole is the main element in Yagi-Uda antenna. ... The main element used here is this folded dipole, to which the antenna feed is given.
