Hi,

I would like to steer the beam pattern of a ULA so its at -25° and 25°.

My code is shown below:

c = 3e8;

fc = 2e9;

lambda = c/fc;

NoOfTxAntenna = 4;

txarray = phased.ULA('NumElements',NoOfTxAntenna,'ElementSpacing',lambda/2);

steer_ang = [25;0];

stv = phased.SteeringVector('SensorArray',txarray);

w = stv(fc,steer_ang);

figure,

pattern(txarray,fc,[-180:180],0,...

'PropagationSpeed',c,...

'CoordinateSystem','polar',...

'Type','powerdb', ...

'Weights',w)

Currently the beam pattern is as shown below.

Many thanks
