Abstract

In this paper, a simple dual-band polarization conversion metasurface(PCM) is proposed. This polarization conversion metasurface can be used in 5G applications such as satellites and radar. The polarization conversion is achieved by etching trapezoidal slots on the upper surface of the metasurface unit, resulting in a change in the distribution of the surface current. To achieve a dual-band, an additional resonant frequency is excited by loading two metal vias and two slots on either side of the metal via. In addition, the tuning of the frequency and the control of the operating bandwidth can be achieved by changing the radius size of the meta via and the slot width of the metasurface unit. The simulation results show that the line polarization(LP) conversion to line polarization(LP) is achieved at 37.6~59.5 GHz and 63~75.6 GHz with the average polarization conversion ratio of 94% and 96% in the two bands, respectively, and the lowest polarization conversion ratio of 90%.
