Integrated Design and Simulation of Conformal Antenna and Frequency Selective Surface

In this paper, based on the theoretical design of conformal antenna and Frequency selective surface(FSS), the conformal antenna and FSS array are modeled and simulated by finite element method (electromagnetic simulation software Ansys HFSS, and the optimal distance between the FSS structure and the conformal antenna is determined. The effect of FSS and antenna frequency on the gain pattern under the condition of optimum distance is studied. The design results show that after the optimal distance between the antenna and the FSS array is determined, the performance of the antenna will be greatly affected when the operating frequency of the FSS is different from that of the antenna. Therefore, When designing the integrated structure of conformal antenna and FSS, it is necessary to co-design and simulate the system composed of conformal antenna and FSS.
