... benefits of deploying more than three antennas are not as relevant (0.6 bit/s/Hz for an optimally designed three-element array with uniform spacing 3.6 λ); (iii) compared to the λ/2-uniformly spaced ... array provided with four uniformly λ/2 spaced antennas. Similarly as before, we compare this result with the case of a line -of- sight channel (Figure 7(a)), where the optimal spac- i...
