Phased Array Design Toolbox v2.4.2



10 Feb 2009 (Updated )

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

% Example using plot_theta/phi_geo1 (extpgeo)
% An example showing the use of the plot_theta_geo1 and plot_phi_geo1 
% commands to display 2D theta pattern cuts on the specified 
% 3D geometry plot. See plot_geom3d1 for plotting geometry on figures
% other than figure1 
% The plot_theta_geo1 and  plot_phi_geo1 commands allow the plot colour
% and figure number to be specified.
% The example uses a 4 x 1 array of circular patches (0.7 lambda spacing),
% orientated vertically to show Azimuth and Elevation patterns.
