I need to design a transmitter antenna having 32db gain and 1 degree beamwidth in simulink. I already used 'narrowband Tx' block and attained a gain of 24db approximately with a 12by12 array. This array size is too much as I want to use 3by2 array size.I want to increase its gain by adding a parabolic reflector. I don't know where to start from and if there is any block or function that will be of aid? If not then any references through which I can compute a code and add to it. Thank you

I'm not familiar with this, but a 1 degree beamwidth does seem to require a large array unless the element spacing is huge in the 3x2 array. In that case, it is almost saying that your array has very limited scanning region if any?

I will do mechanical scanning with this beamwidth. Okay, I plotted radiation pattern with 12by12 array and I got 27db gain. Let's say with 4by4 array I get 12db gain and I want to add parabolic gain to it in order to make 32db gain. In simulink do I simply have to add a Gain block of 20db( 32-12)? If yes then how is it going to be added in my narrowband tx block?

or do I have to make an array of 32db and gain block of 32 db as well?
