Yagi-uda Wire Antenna Pattern Plotting, Assignments of Wireless Communication Systems

National Institutes of Technology (NITs)Wireless Communication Systems

Instructions on how to plot the pattern of a Yagi-uda wire antenna. It includes the necessary parameters such as frequency, dipole radius, number of directors, reflector length, fed element length, spacing between reflector and fed element, and spacing between directors. The document also provides the length of directors and the calculation of L, r, l, L1, L2, L3, L4, r1, and r2. useful for students studying antenna design and wireless communication.

EXPERIMENT NO:- {3}
OBJECT:-Plot the pattern of “YAGI-UDA” wire antenna-
Given :-
Frequency =1 Ghz and Dipole radius(r) is L/100
Number of Directors are 4.
Ans. :-
We know that Reflector length (L) is = 0.48C/f and
Fed Element length(l) is =0.46C/f,
Spacing between Reflector and Fed Element(r1) is =0.25C/f.
Spacing between Director a andDirector bis(r2) =0.31C/f. ( where a,b are
1,2’2,3’3,4).
Length of Directors(L1,L2,L3,L4) is 0.44C/f,.043C/f,0.40C/f respectevelly.
SO that By calculation :-
L=14.4 cm,r=0.144cm ,l=13.8 cm
L1=13.2cm,L2 =13.2cm, L3 =12.9cm,L4 =12.0cm
r1=7.5cm,r=9.3cm.
