Abstract
The present invention provides a reflective array surface. The reflective array surface includes a functional board that is configured to perform beam modulation on an incident electromagnetic wave and a reflection layer that is disposed on one side of the functional board and is configured to reflect an electromagnetic wave, where the functional board includes two or more functional board units and the reflection layer includes reflection units, where the number of reflection units corresponds to the number of functional board units, where the functional board unit and a reflection unit corresponding to the functional board constitute a phase-shifting unit that is used for phase shifting. According to the reflective array surface in the present invention, a functional board unit and a reflection unit corresponding to the functional board unit constitute a phase-shifting unit that is used for phase shifting, which can solve a problem in the prior art that a phase-shifting effect is not exquisite enough and a beam modulation capability for an electromagnetic wave is poor, thereby affecting bandwidth and working performance of a reflective array antenna. In addition, the present inve…
