Vanishing spectrum at higher frequency

So the measured spectrum of the signal I'm analyzing is repeated several times in frequency domain with fs = [sample rate] spacing, as theory teaches, but I see spectra at n*fs with increasing abs(n) becoming increasingly less intense than the one centered on 0.

What may that be due to?
