Problems solved by technology

There are two main problems in beam scanning using phase shifting and excitation amplitude enhancement: one is that there are a large number of related components such as phase shifters, which increases the hardware cost and the space occupied by the device; the other is that there are many beams, and the beam The narrower makes the scanning period larger, the response speed is poorer, and the power consumption is increased
