摘要

在这项工作中，提出了一种采用两个同心圆环和一个十字的x波段反射天线。为了提高单元电池的相灵敏度，设计并分析了三种类型的单元电池。设计了尺寸为205.7 mm × 205.7 mm的中心馈源反射天线。它在10ghz时具有26dbi的优异增益。孔径效率为67%，旁瓣电平为-15.6 dB, 1 dB带宽为12%。

An X-Band Reflectarray Antenna Using Concentric Rings and a Cross

In this work, an X-band reflectarray antenna using two concentric rings and a cross is proposed. Three types of unit cells are designed and analyzed to improve the phase sensitivity of the unit cell. A center-feed reflectarray antenna with dimensions of 205.7 mm x 205.7 mm is then designed. It performs an excellent gain of 26 dBi at 10 GHz. It also achieves a good aperture efficiency of 67%, a sidelobe level of -15.6 dB, and a 1-dB bandwidth of 12%.
