Hello
I am trying to plot the Figure 5 (Magnitude of the output as a function of the arrival angle for Antenna Array):http://www.antenna-theory.com/arrays/main.php
But it seems like it is not so simple.

I wrote this simple code but I do not have the desired result:

teta_angle = 1:0.25:180;
y1= exp(-j*pi*cos(teta_angle));
y2= exp(j*pi*cos(teta_angle));
y=y1+y2;
Y=mag2db(abs(y));
plot(teta_angle,Y)


Could you maybe help me to figure out what is wrong with my code ?

Thanks

Looks like your taking cosine of an angle in degrees, should be radians

Actually I found it, thank you
