step method of phased.URA: where is my phaseshift?!

I want to get the sensor array complex response ratios from an angle. I try to use phased.URA.step(freq, angle), but it gives me equal numbers for each element for any angle.
Here is a small example:
ant_array = phased.URA();
disp(ant_array.step(3e8, [45; 0]));
It gives me a result:
1
1
1
1
Can anyone tell me, what does it mean and how can I use angle parameter correctly?

The return you see is the response of each element at the specified degree. There is no phase shift between them. If you want to see the phase shifts between them, you can use SteeringVector, e.g.,
ant_array = phased.URA();
stv = phased.SteeringVector('SensorArray',ant_array);
disp(stv.step(3e8,[45;0]))
