A folded dipole is a dipole antenna with the ends folded back around and connected to each other, forming a loop as shown in Figure 1. Figure 1. A Folded Dipole Antenna of length L. Typically, the width d of the folded dipole antenna is much smaller than the length L.
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.
Oct 25, 2020 · A Folded dipole antenna is used in Yagi-Uda antennas for terrestrial television (TV) reception using the balanced line of Z 0 = 300 Ω because a folded dipole antenna has a high input impedance and hence it is easily matching with the impedance of the transmission line.
A folded dipole antenna is basically a dipole antenna with both ends connected by a rod or wire. It’s folded in a closed tubular shape. One interesting fact is that the dipole’s length is basically the wavelength’s half, which is why it’s also known as a half-wave dipole antenna.
Jan 15, 2022 · The folded dipole antenna is ideal for use as a feeder element in Yagi antenna, Parabolic antenna, turnstile antenna, log periodic antenna, phased and reflector arrays, etc. It is also used in radio receivers and is commonly used in TV receiver antennas.
The folded dipole antenna is an extremely practical wire antenna and is also called an ultra closed spaced array. It consists of two parallel, closely spaced λ/2 dipoles joined together at the outer ends forming a narrow wire loop (d << L and d << λ).
Folded Dipole. The folded dipole is a very popular wire antenna, for a number of reasons: Impedance properties (easy to match, as we will see); Ease of construction; Structural rigidity; Wider bandwidth than. =2 dipole (not proved here). The structure of a folded dipole is shown below.
