摘要
设计一种工作在L频段的1×8阵元的微带阵列天线。天线阵元采用双层微带天线形式,在天线阵元间加载金属隔板,降低阵元间的耦合,并设计了天线馈电网络。经过仿真和制作,天线在装配天线罩后的高度只有空间工作波长的0.16倍,并在16%的相对带宽内驻波比小于2.0,天线的水平面副瓣低于-24 dB。
A microstrip array antenna with 1×8 elements operating in the L-band is designed.The antenna array element adopts a double-layer microstrip antenna form;Metal spacers are loaded between the antenna array elements to reduce the coupling between array elements.And antenna1feeding network is designed either.After simulation and fabrication,the height of the antenna after assembly of the radome is only 0.16 times the spatial operating wavelength.The VSWR is less than 2.0 in the 16%relative bandwidth.The horizontal side lobes of the antenna are lower than-24 dB.
