Analysis and Design of Dual-Polarized Time-Share On-Off Bandpass FSS

Coping with the technical demand of radar stealth, a dual-polarized time-share on-off FSS is simulated in this article. Through the adaption of three layers of CLC compound structures and time-sharing control under the operation of switching diodes with dual and independent control, the proposed structure realized the autonomous regulation between transmission and rejection under TE and TM polarization. The optimum and performance of proposed structures are simulated by the full-wave EM simulation software. Simulation results indicate that this structure realized autonomous regulation between four states, i.e., dual-polarized transmission, single-polarized transmission Isingle-polarized rejection, and dual-polarized rejection. The insertion loss of passband less than IdB ranges from 8.5 to 11.5 GHz, and the stopband of transmission coefficient less than 10dB ranges from 7 to 10 GHz. Moreover, results support the fact that proposed structures realized the autonomous regulation between effective transmission and efficient rejection in desired polarizations. Results denote that the proposed dual-polarized time-share on-off FSS in this article is feasible.
