Ultra-Low-Loss Reflectarrays with Wide Scanning at 28GHz and 140GHz Using RFSOI

This talk presents the design and measurements of wide-scan-angle reflectarrays at 28GHz and 140GHz. The arrays are very low power and with a loss of <4dB, making them state-of-the-art. Furthermore, they result in excellent patterns and low aperture loss due to the 4 bit nature of the phase shifters on each element. Demonstrations in 5G/6G will be shown.
