How many carriers for phased array?

[sophiecentaur]

as far as the angular range to operate is concerned, the desirable limit would be 5 degrees,

What do you mean by this statement? How does this relate to the situation?

I mean it would be desirable to have a very collimated and directional beam with the same directionality as a laser, but with that wavelength it would be difficult, that was just my guess

@sophiecentaur So, what antenna size is best for my purpose? I'm just missing this information, but I can't seem to find the right path. I believe the half-wave antenna will provide more stability, but I'm looking for your opinion, which is much more valuable.

You haven't stated your "purpose" so there is no answer. Are you aware of the theory that applies to multiple element antennae?

This is nonsense in the context of a small array and the RF frequency you propose. Are you aware of the formula for the limiting width of a beam, given the wavelength and aperture of the array? I think some homework is called for. There's no point in my telling you about this; you have to do some searching about multi-element arrays. Google is full of that information and you need to have an idea about it if you plan to have a working system.
I suspect you may be in the world of simulation and not the practical world

@sophiecentaur yes yes I already knew that the focal point of the array depends on the aperture of the array itself and on the wavelength, and I did the calculations for near field focusing and the Frasnel distance is around 50 and 70 cm away, but I don't understand what this has to do with the choice of the size of the antenna, whether half wave or quarter wave, yes I am a beginner and I study every topic that I don't know, but since I am a beginner I am here asking questions, if I knew everything I wouldn't be here.

Perhaps you can gain intuition regarding the kind of beams that can be formed from a phased array of antennas by playing with on-line calculators. For example, here's one that allows you to adjust the number of antenna elements, their spacing and relative phase shifts:

Here's another that lets you choose the specific type of the individual antennas:

But do bear in mind that these calculators model a linear (1D) $n$-element array of antennas. If you desire a beam that is narrow in both transverse directions, you require a 2D rectangular array of $n^2$ elements. That amounts to 100 antennas for the second case above and a whopping 324 in the first!
