Hello,
Just was curious to know that λ/2 spacing should be pitch of the array or the kerf of the element spacing??
We know that:
pitch(centre to centre spacing)= 2*a(half of the width of each element) + kerf(edge to edge spacing)
If the spacing is less than λ/2 then there is increase of mutual coupling and interference and if the spacing is more than the main lobe is divided in more than one side lobes thereby formation of grating lobes.
