摘要

本文介绍了一种工作频率为20ghz的菱形环槽单元反射天线的设计与研究。设计中采用的菱形环槽可以延长单元的反射相位范围。反射天线的尺寸为190 × 190 mm2，圆形孔径共505个单元，焦距为150 mm。提出了一种对称波束宽度为35°、增益为14.4 dBi的矩形喇叭天线作为天线馈源。设计的天线增益提高到27.2 dBi，指向$\bm{ (\theta = 0^{\circ}, \phi=0^{\circ})}$，波束宽度为5.8°。

A Reflectarray Antenna Based on Diamond-Ring Slotted Elements With Enhanced Reflection Phase

This paper presents the design and investigation of a reflectarray antenna with diamond-ring slotted elements operating at a frequency of 20 GHz. The diamond-ring slot applied to the design can extend the reflection phase range of the unit-cell. The reflectarray antenna has a dimension of 190 × 190 mm2 with a total of 505 elements in a circular aperture and a focus of 150 mm. A rectangular horn antenna with a symmetric beamwidth of 35° and 14.4 dBi gain is proposed as the antenna feed. The designed antenna has improved gain with a value of 27.2 dBi directed to $\bm{ (\theta = 0^{\circ}, \phi=0^{\circ})}$ and a 5.8° beamwidth.
