Abstract
A novel integration method of a polarization conversion metasurface (PCM) and an array antenna for radar cross-section (RCS) reduction is presented. This method combines the PCM with a slot array antenna operating at 11.5 GHz for reducing RCS. The metasurface is composed of polarization conversion units arranged in a checkerboard pattern, and each PCM unit cell is made up of two symmetrical fork-shaped structures. The polarization conversion units can achieve a polarization conversion rate of over 90% in the frequency band of 10.12-19.93 GHz (65%). The measurements demonstrate that the antenna attains over 10 dB RCS reduction in the frequency range of 9.9-20.7 GHz (71%). Meanwhile, the radiation performance of the antenna is effectively preserved.
