Summary:
A spatial modulation module consisting of an array antenna and dual scatterers was demonstrated. A circularly polarized microstrip 2x2 array antenna for the 5.8-GHz power transmission band was designed and fabricated. The measured gain was as high as 13.9 dBi, and the axial ratio was 1.22. With an array antenna for the transmitting antenna, spatial modulation characteristics were measured in both frequency and time domains for 1-MHz sine- and square-wave inputs. A modulated signal was clearly observed for both the spectrum and the waveforms of the received voltage. The measured amplitude modulation factor was 6%.
