I don't think it has. Bandwidth depends on the diameter to length ratio of the antenna. The greater the diameter of the elements the wider the bandwidth. The inductance goes down and the capacitance goes up, giving the antenna a lower Q. the folded dipole has a greater effective diameter (at least double for the same materials). You can increase a normal dipole's bandwidth by increasing the diameter, hence the old time birdcage aerials.

CoachCompared to a simple dipole, a folded dipole antenna has a different radiation
pattern with higher 'gain' in its preferred direction, a balanced feed-point, and
four times the feed-point impedance at resonance.
If those happen to be the characteristics you're looking for in your application,
then the folded dipole is exactly what you need.

Who discovered the antenna?
yagi uda
Why yagi uda antenna is used?
Some advantages of the Yagi- Uda Antenna include that this is a widely used design and low cost. The construction also is simple. Some disadvantages are that the receiver of the Yagi-Uda Antenna may have problem receiving signal.
Is parasitic elements are used in yagi-uda antenna?
Yes - reflector element and directional elements.
How many directors and reflectors in Yagi Uda antenna?
yagi udda antenna has only one reflector...but it has many directors...depending upon gain and efficiency...the length of reflector is normally...more than one-half of wavelength... and directors have a length less than one-half of wavelength...
What is the difference between Log Periodic and Yagi Uda antennas?
The Yagi consists of one driven element, plus one or more shorter elements acting as directors placed in front of it, plus one or more longer elements acting as reflectors placed behind it. Technically, the driven element is cut and the feed system is matched for a specific frequency ... the farther from that frequency, the more the performance of the Yagi degrades.The Log Periodic array consists of a uniformly tapered array of many elements. The lengths of the elements and the spacing between them decrease by a constant ratio as you move down the array, and all of the elements are electrically connected to the feed line.The objective is an array that's very broad in frequency. The idea is that at any given frequency within the total range of the array, the element closest to a resonant length will radiate/receive best, those in front of it will function as directors, and those behind it will function as reflectors.
