Research has been conducted on the problem that it is not easy to balance the scattering performance and radiation performance of low-scattering microstrip antennas. A radiation-scattering integrated microstrip antenna based on miniaturized frequency selective surfaces was designed. The method of adopting the bent arm of the frequency selective surface unit to increase the equivalent length of the frequency selective surface arm was used to miniaturize the size and structure of the frequency selective surface. By optimizing the parameters between the wedge-shaped frequency selective surface radome and the microstrip antenna, the radiation performance of the microstrip antenna within the operating frequency band was enhanced, and the radar cross-section of the microstrip antenna in the wide frequency band was reduced. The calculation results show that the size of the frequency selective surface was reduced by 18.5% compared with the original structure. It was achieved that compared with the original antenna, the radiation gain of the radiation-scattering integrated antenna increased by 0.26 dB, and the average radar cross-section within the frequency range of 1 - 18 GHz was -28 dB.
