traveling

gain of traveling-wave antenna of length L

Calling Sequence

[g,th,c,th0] = vee(L,Nth);

Parameters

L

length in units of lambda

th

Nth+1 equally-spaced polar angles in [0,pi] = (0:Nth)*pi/Nth

g

g(th)=c*[sin(th)*sin(pi*L*(1-cos(th)))/(1-cos(th))]^2

c

unity-max normalization constant

th0

acos(1 - 0.371/L) = direction of main lobe in degrees.

Description

vee(L, alpha, Nth) computes gain of traveling-wave antenna of length L.
