The windmill-shaped antenna achieves a short distance between the two bands for f1 =3.4GHz and f2=3.6GHz with high gain in 5.61dBi and 4.08dBi in a compact size (43.75mm*43.75mm*1mm).

The structure is originated from the traditional two-way single-phase shifter, while the incident waves from space are converted to guiding waves through 3-D stacked slot line structures firstly. Then the guiding waves propagate along two different ways controlled by four PIN diodes, and finally convert to space waves again via 3-D stacked slot line structure. The two states have a phase difference of 180 deg., which is achieved by choosing two strip lines with different lengths.

The 2-bit reflection phase states “00” (0°), “01” (90°), “10” (180°), and “11” (270°) were generated by rotating the E-shaped metallic resonators. The RCS reduction mechanism is achieved by randomly distributing the four coding states of the 2-bit sequence across the proposed metasurface aperture. The RCS reduction is achieved by strongly diffusing and redirecting the reflected energies to all angles in the space in front of the proposed 2-bit metasurface. The simulated results show that the proposed 2-bit metasurface maintaining more than 10 dB of RCS reduction from 13 GHz to 22 GHz. The RCS reduction fractional bandwidth (FBW) under normal incidence of CP plane wave is 51.4%, compared to a bare metal plate with the same size.
