摘要
VICTS天线显著的低剖面、高增益和宽波束等优点使其在移动通信领域具有巨大应用潜力。本文阐述了VICTS天线的结构特点和波束扫描形式,推导了各层圆盘的角度变换关系。结合天线的实测增益变化曲线,设计了基于分段多项式拟合的增益补偿方法,经该方法补偿后的增益变化约为0.15 dB。三轴摇摆试验结果显示,摇摆过程中场强信号稳定,波动最大约0.25 dB,满足VICTS天线的动态使用需求。
The VICTS antenna has significant advantages such as low profile,high gain,and wide beam,making it have great application potential in the field of mobile communication.The structural characteristics and beam scanning forms of the VICTS antenna are first expounded in this paper,the angle transformation relations of each layer of the disk are deduced.Then,combined with the measured gain variation curve of the antenna,a gain compensation method based on piecewise polynomial fitting is designed.The gain variation after compensation by this method is about 0.15 dB.Finally,a three-axis rocking test is carried out.During the rocking process,the field strength signal is stable,and the maximum fluctuation is about 0.25 dB,which meets the dynamic usage requirements of the VICTS antenna.
