%DEFANT_S S-function for antenna definition.
%
%--------
%Synopsis:
%  [sys,x0,str,ts] = pantpat3_s(t,x,u,flag,restParam) 
%
%Description:
%  S-function for antenna definition.
%
%  The general form of an M-File S-function syntax is:
%    [SYS,X0,STR,TS] = SFUNC(T,X,U,FLAG,P1,...,Pn)
%
%  Optional parameters, P1,...,Pn can be provided to the S-function and
%  used during any FLAG operation.
