| 摘 要： | 设计了一种结合了"十"字和圆环的新型宽带W波段Flaps(Flat Parabolic Surface antenna)天线单元。相比于传统的单层Flaps天线单元,新型单元能获得更宽的相位范围且相移精度更高,能有效拓展天线的带宽。利用这种单元设计了94 GHz的单层Flaps天线,仿真结果显示了较好的带宽性能和方向性,中心频率处增益18.2 dBi,在10.6%的带宽内增益下降小于1 dB,实现了较好的宽带性能,为单层W波段Flaps天线的设计提供了一种新途径。

| Abstract: | A novel broadband W-band Flaps antenna phase-shifting element which the crossed-dipole with annulus patches is proposed in this paper. Compared to the conventional sing-layer Flaps antenna element, the novel elements can realize much larger phase variation range and higher precision of phase shift as well as expand the bandwidth of the antennae effectively. Based on this element, a single-layer reflectarray antenna operating at 94 GHz is designed. The simulation exhibits perfect performance in the bandwidth and directivity, the 1-dB gain bandwidth which is close to 10.6% is obtained and the peak gain of the center frequency is 18.2 dBi. This proposed element offers a new way to design single-layer millimeter-wave reflectarray antenna. |
