From a patent spec someone skilled in the art ought to be able to make a CFA without assistance from the inventor. Having read the spec I have come to two conclusions: 1) I am not skilled in the art 2) the First Law of Engineering applies (any useful advance has at least one major disadvantage). In this case I wonder if, as we make the CFA a smaller and smaller fraction of a wavelength, it becomes more and more difficult to maintain the correct relative phasing and amplitude of the two feeds? Would someone skilled in the art like to comment?
