want to create phased array antenna as shown in picture

I want to create phased array Txantenna as shown in picture and using this antenna will model radar transmision using phased.Radiator.

kindly help me ,how this antenna can be created using phased array tool box.

TX2

TX1 1 TX3

where, 1 is used to just represent centre point

horizonatal distance between TX1 antenna and 1 is lambda

horizonatal distance between 1 and TX3 antenna is lambda

horizonatal distanc 1 and TX2 antenna is lambda/2

You can use a phased.ConformalArray to represent an array with arbitrary element positioning - https://www.mathworks.com/help/phased/ref/phased.conformalarray-system-object.html

Assuming we are looking down on the x-y plane, with 1 being the origin, and the y axes pointing up, you could do something like this:

lambda = 1; % set this to your desired lambda
pos1 = [-lambda;0;0];
pos2 = [0;lambda/2;0];
pos3 = [lambda;0;0];
array = phased.ConformalArray('ElementPosition',[pos1,pos2,pos3]);

Assuming the antenna elements that you wish to model are isotropic, that is all you need to do, otherwise you need to be careful that the array normal is set correctly.

hi george thanks for answering,its working.
