rhombic

gain of traveling-wave rhombic antenna

Calling Sequence

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

Parameters

L

length in units of lambda (L=0 not allowed)

alpha

vee half-angle in degrees

g

g(th)

th

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

c

unity-max normalization constant

th0

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

Description

rhombic(L,alpha,Nth) computes gain of traveling-wave rhombic antenna. (alpha*Nth/360 must not be an integer)

Examples
