摘　　要：利用PIN管实现反射阵列天线单元补偿相位的改变,使得反射阵列天线完成快速的双频宽角度电子波束扫描。天线结构为12×12反射天线阵列,通过在天线单元上添加PIN管,并编程控制PIN管的导通截止,可进行反射阵列天线双频宽角度电子波束扫描。仿真和实验表明,反射阵列天线在3.82 GHz和4.52 GHz均可实现±45°波束扫描,实测3.82 GHz增益为10 dB左右,4.52 GHz增益为13 dB左右。The PIN diodes was used to realize the change of the compensation phase of the reflec-tarray antenna unit cells,so that the reflectarray antenna could complete the fast wide-angle electronic beam scanning at double-frequency.The antenna structure is a 12×12 reflect antenna array.By adding a PIN diode to the antenna unit cell and programming to control the conduction and cut-off of the PIN diode,the reflectarray antenna could be scanned with dual-frequency and wide-angle beams.Simula-tions and experiments show that the reflectarray antenna can achieve±45°beam scanning at 3.82 GHz and 4.52 GHz.The measured gain of the reflectarray antenna is about 10 dB at 3.82 GHz and 13 dB at 4.52 GHz.
