Phased Array Design Toolbox v2.5



10 Feb 2009 (Updated )

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

% Shows the 3D pattern and array geometry for a 64-element
% rectangular array array of patches.
% The array is squinted to theta=25, phi=45deg.
% The array element pitch is 0.6 lambda
% The array element is :
% Single rectangular patch
% Freq = 2.45GHz
% Er   = 3.43 (Rogers 4350)
% h    = 1.6mm
