However, the millimeter wave radio frequency chip is required to integrate devices such as a phase shifter, a low noise amplifier, a tapping amplifier, a switch, a filter and the like, and the high integration means the cost is increased; on the other hand, because the chip volume has clear size requirements in occasions such as mobile phones and base stations, the chip cost reduction is more cost-effective by eliminating some devices from the design of millimeter wave modules.
The 5G millimeter wave module consists of a radio frequency chip and a base station antenna, and the radio frequency chip mainly aims at providing a phase-controllable power signal and finally realizing the beam control of the antenna end. If the phase passive control is realized from the antenna end, the chip end does not need to design a phase shifter, so that the chip volume is reduced, and the chip cost is reduced.

Assume that the current antenna/magnetic current antenna pattern is collectively expressed as:
F(θ)＝e -jkr sin (θ) (equation 1)
Where θ is the angle between the emitted wave and the Z axis, j is the imaginary number, k is the propagation constant, r is the spatial position vector, f is the operating frequency, u is the relative permeability in the medium where the electromagnetic wave is located, and ζ is the relative permittivity in the medium where the electromagnetic wave is located.
According to the electromagnetic mirror principle, the total far field (i.e. the pattern) is a virtual field, the far field of the superimposed current/magnetic current (i.e. formula 1), we can divide the result into 4 expressions:
case 1 and case 6 are one type: f (Δ) =sin (KHcos Δ) (expression one)

Moreover, after the post verification, the distance between the antenna and the ideal magnetic wall should not exceed 0.05λ, otherwise, the situation 5 cannot be satisfied.
Through the design thought and through the later simulation test, the antenna module with the adjustable beam scanning angle is finally developed.

As shown in fig. 5, the operation mode of the super surface module is a reflection mode when the top diode and the bottom diode are in a conducting state, and the dotted line corresponds to the disconnection state of the top diode and the bottom diode, and the operation mode of the super surface module is a projection mode.
The size of the ideal magnetic conductor can be regulated by regulating the number of the super surface units, fig. 10 is a graph of the relationship between the number of rows of the super surface units in the on state and the beam width of the antenna module with the adjustable beam scanning angle, fig. 10, the vertical axis is the beam width, and the horizontal axis is the number of rows of the super surface units in the on state, as can be seen from fig. 10, as the number of rows of the super surface units in the on state increases, the beam of the antenna module with the adjustable beam scanning angle increases, and HPBW is the meaning of the beam angle width.
