Phased Array Design Toolbox v2.4.2

by

 

10 Feb 2009 (Updated )

A toolbox allowing rapid definition and evaluation of 2D and 3D phased array antennas.

excirc1.m
% CIRCULAR POLARISATION  (Method1)
% 
% Crossed dipoles
% Overlaid and fed in phase quadrature to give RHCP in the Z-axis direction
%
% Try the 'lhcp' plotting option for X-polar response (3D and 2D Plots).
% And the 'ar' option to see the axial ratio overlaid on the
% 'tot' pattern (3D only).
