Since microstrip antennas are frequently used in military platforms, antenna design with low radar cross section will contribute to the general efforts towards reducing RCA. First, a microstrip antenna with a center frequency of 5 GHz was designed and a FSS that acts as a reflector at this frequency was developed. Here, the expectation from the FSS is to act as a reflector at the center frequency and to have a transmissive behavior at other frequencies, contributing to the reduction of the radar cross section. By integrating the designed FSS structure into the ground plane of the antenna, RCA reduction was achieved in different bands without shifting the center frequency. According to the simulations, the designed antenna has a 10 dB lower radar cross section in the X band. © 2025 Elsevier B.V., All rights reserved.trinfo:eu-repo/semantics/closedAccessFrequency Selective SurfacesMicrostrip Patch AntennasRadar Cross Section ReductionAntenna GroundsAntenna ReflectorsElectromagnetic Wave AbsorptionMicrowave AntennasRadar AntennasRadar Cross SectionReflectionSlot Antennas% ReductionsAntenna DesignCentre FrequencyFrequency-Selective SurfacesMicro-Strip Patch AntennasMicro-StripsMicrostrip-Patch AntennaMilitary PlatformsRadar Cross-SectionsMicrostrip AntennasConference Object10.1109/SIU66497.2025.111118132-s2.0-105015469472
