摘要：
The present paper proposes a design method for synthesizing a frequency selective surface (FSS) based dual-band composite radome wall with high angular stability. In the proposed method, a generalized composite structure composed of two FSS arrays embedded within dielectric layers has been adopted to obtain the dual-band second-order band-pass transmission characteristic. To describe this transmission characteristic, a novel equivalent circuit model has been established. By this equivalent circuit model, the optimized structural parameters can be derived from the desired resonant frequency and bandwidth of the pass-bands via a curve-fitting method. Also, discussions and principles for designing the dielectric layers have been provided to achieve the high angular stability. The simulated results show that the designed radome wall can provide two pass-bands operating at 10GHz and 14GHz with a bandwidth of 2GHz and 1.8GHz, respectively. And the two pass-bands are stable at 60 degrees incident angle for both TE and TM polarizations. For verification, a dual-band composite radome wall has been designed, fabricated and measured. Good agreements between the simulated and the measured results can be observed.
