Abstract

An ultrawide passband and dual-polarized frequency-selective surface (FSS) for the K-Ka frequency band is presented. The characteristics of wide passband, angular stability, and fast roll-offs are realized by using LC resonant structures and multilayer coupling. The whole structure of the FSS cell is symmetrical, realizing TE and TM polarization. A prototype of the proposed FSS is manufactured and measured. The size of the prototype is $123.6\times 123.6\times 2.961$ mm. The measured results have a good agreement with the simulated ones. The measured passband is from 18.3 to 37.2 GHz (K-Ka frequency band), of which the relative bandwidth is 68.1%. Moreover, the passband has little change within the incidence angle ±40° for both TE and TM polarizations. Therefore, the FSS can be widely used in the communication system.
双极化超宽通带频率选择表面
提出了一种用于K-Ka频段的超宽通带双极化选频表面。利用LC谐振结构和多层耦合实现了宽通带、角稳定和快速滚降的特性。FSS单元的整体结构是对称的,实现了TE和TM极化。制造并测量了所提出的FSS的原型。样机尺寸为123.6 × 123.6 × 2961 × mm,实测结果与仿真结果吻合较好。测得的通频带为18.3 ~ 37.2 GHz (K-Ka频段),相对带宽为68.1%。此外,在入射角±40°范围内,TE极化和TM极化的通带变化不大。因此,FSS在通信系统中可以得到广泛的应用。
