Reduction of radar cross section of patch antenna using modulated metasurface
A research work aimed at reducing radar cross section (RCS) and enhancing gain of the patch antenna by using modulated metasurface structure, without degrading the radiation performance, is proposed in this paper. The operating frequency is 10.5 GHz. In addition, the modulated metasurface is achieved by changing the rotation angle and size of elements of unit cell of metasurface structure. Simulated results demonstrate that the proposed modulated metasurface structure can reduce the RCS significantly in the operating frequency range of 6 GHz to 14 GHz for both X-and Y-polarizations which makes it promising in various applications. Average reduction for the complete frequency range is approximately 70dB and gain enhancement is 4.5 dB. The design is simulated on HFSS v.16.
