The split ring resonators (SRR) is designed to work at X band and its equivalent medium parameters are estimated by using the equivalent analysis method. The high gain microstrip antenna, which is based on Photonic BandGap (PBG) structure, is also studied. To make the scattering wave deviates mirror direction and reduce the out-band Radar Cross Section (RCS) without affecting the performance of antenna, the designed SRR is used as the cover of PBG structure microstrip antenna. The results show that the forward gain of PBG structure antenna is 0.8 dB higher than the tradition antenna. After the SRR covers on the PBG structure antenna, the gain of antenna is unchanged and the RCS of the mirror direction decreases for all incident angles, and the most decrement is 21.05 dB.

AbstractIn this paper using Plasmon Resonances Management (PRM), a bi-functional meta-mirror is proposed in which, the meta-mirror can obtain two opposite properties in two different frequency ranges. In this method, an anisotropic unit cell with polarization conversion property is modified to have two plasmon resonances in both symmetric and anti-symmetric planes in a specific frequency. This allows the unit cell to have the property of unchanged polarization in that frequency. The meta-mirror is composed of this modified unit cell and its mirror as a chessboard arrangement and the incident wave on the meta-mirror is reflected as in-phase in that specific frequency i.e. specular reflection, while as out-of-phase in other frequencies i.e. RCS reduction. The designed meta-mirror in this paper demonstrates the RCS reduction in two side-bands from 4 to 9 GHz and 10.8 to 14.8 GHz while behaving as a specular reflection in the frequency around 10 GHz.
