摘要
本文介绍了一种工作在Ka波段的折叠反射天线。交叉偶极子元件能够提供超过420°的调谐相位范围，用于构造反射反射。通过仿真和实验验证了设计的正确性。在总体尺寸为210 mm × 210 mm × 45.5 mm的情况下，测量获得了27.3 dBi的峰值增益和27.7-31 GHz的3db增益带宽。E面和H面旁瓣电平分别小于- 20.5 dB和- 18.5 dB。
In this paper, a folded reflectarray antenna operating at Ka band is presented. A crossed-dipole element, which is able to provide a tuning phase range of more than 420° is used to construct the reflectarray. Simulations and experiments are conducted to validate the design. With the overall size of 210 mm × 210 mm × 45.5 mm, a peak gain of 27.3 dBi and a 3 dB-gain bandwidth of 27.7–31 GHz have been achieved in measurements. Sidelobe levels are less than −20.5 dB and −18.5 dB in the E and H planes, respectively.
