Antennas And Wave Propagation
5.4 Folded Dipole Antenna It is the important modification of the conventional half
wave dipole in which the two half wave dipoles have been folded and joined
together as shown in the Fig. 5.7. One of the half wave dipoles in continuous
while ...

Approximate Antenna Analysis for CAD
In the remainder of this chapter, we shall outline the analysis of the input
impedance of a symmetric wire folded-dipole antenna, where we shall use the
concept of separating the dipole mode and the transmission line mode. This
analysis is ...

Antennas and Wave Propagation
iii) Folded dipole : A folded dipole is obtained with two conventional half wave
dipoles; one continuous and other splited at are folded and connected together in
parallel at the ends. A typical folded dipole antenna with its current distribution ...

13.12 FOLDED DIPOLE An ordinary y dipole antenna has an impedance of
about 72 Q at the feed point. This impedance increases to four times its value (72
x 4 = 288 Q) by converting it into a folded antenna rod construction in which the
half ...

The ARRL Extra Class License Manual for Ham Radio
The folded dipole! Now, during each half cycle, the direction of current flow is
shown by the arrows in the figure. Just remember that current flow reverses in the
conductor at B and C. Why does the antenna impedance change? First, the
power ...

Antenna and Wave Propagation
Folded dipole antenna differs from the conventional dipole mainly in two respects
: directivity and wider bandwidth. The directivity of folded dipole antenna is bi-
directional but because of the distribution of current in the parts of the folded
dipole ...

TV and Video Engineering
At lower frequencies, the thickening of the conductors may be conveniently
achieved by using conductors separated by'O.lA or less connected in parallel, in
place of strip or conical sections (see Fig. 9.5). 9.3 FOLDED DIPOLE The
impedance ...

pattern, is flatter than the dipole The dipole half-power beam width is about 90°,
while that for the folded dipole is about 50°. This is attributable to the array nature
of the folded dipole. The dipole 3-D pattern side and front views are illustrated in
...

Antenna Theory: Analysis and Design
A half-wavelength, two-element symmetrical folded dipole is connected to a 300-
ohm “twin-lead” transmission line. In order for the input impedance of the dipole
to be real, an energy storage lumped element is placed across its input terminals.
