Phased Array Design Toolbox v2.5



10 Feb 2009 (Updated )

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

function [EleAmp,CPflag]=sumcode(Elt,thloc,philoc)
% Returns element pattern data and circ-pol flag showing whether or not 
% it is inherently circularly polarised e.g. Helix.
% Usage: [EleAmp,CPflag]=sumcode(Elt,thloc,philoc)
% Elt.....Element type (numeric code)
% thloc...Local theta coords (radians)
% philoc..Local phi coords (radians)
% Returned value:
% EleAmp........Element pattern value in direction of 
%               local (theta,phi) coords
% CPflag........Circular polarisation flag.
