摘要：

In this letter, a polarization conversion metasurface antenna (PCMA) array for stealth design method is proposed. The array is composed of polarization conversion metasurface (PCM) subarray and their mirror subarray, which simultaneously plays the role of antenna element and PCM. So that, a certain phase cancellation can be produced between subarray and mirror one. The backward scattering is canceled while the radiation performance is maintained. This method has the characteristics of simplicity, low profile and easy to be implemented. Average area occupied by each antenna element can be reduced to 0.15 lambda 02. Simulation and measured results show that the maximum reduction of monostatic RCS of aforementioned PCMA is 16.3 dB in 8.2-13.6 GHz band, and the relative bandwidth of effective RCS reduction (more than 10 dB) reaches 34%, which verifies the effectiveness of the polarization cancellation design method based on the integration of array elements and PCM.
