Using phased.MVDREstimator2D with conformal array and custom antennas.

I am trying to perform angle of arrival estimation using phased.MVDREstimator2D, with a 4-element conformal array consisting of a custom antenna type.

ant = phased.CustomAntennaElement;
ant.MagnitudePattern = G; % G is a 181x361 antenna magnitude pattern in dB. Obtained from real antenna.
ant.PhasePattern = P; % P is a 181x361 antenna phase pattern in degrees. Obtained from real antenna.
array = phased.ConformalArray;
array.Element = ant;

ypos = [-9 -1.5 1.5 9].*0.01;
xpos = [-1 0 0 -1].*0.01;
zpos = [0 0 0 0];
normal_az = [-45 0 0 45];
normal_el = [0 0 0 0];
array.ElementPosition = [xpos;ypos;zpos];
array.ElementNormal = [normal_az;normal_el];
array.ElementPosition = [xpos;ypos;zpos];

My question is: does the MVDR estimator take into consideration the magnitude and phase of the custom antenna type? When I use the estimator, the spatial spectrum is identical to when I just set ant.MagnitudePattern and ant.PhasePattern to zeros.

Many thanks in advance.
