| 摘 要： | 利用时域有限差分(FDTD)方法,研究了入射脉冲分别为水平和垂直极化时,探针馈电和微带馈电两种结构对于微带贴片阵列天线后向散射场的影响.给出了散射场的时域波形以及频谱特征.结果表明:微带天线阵列的每个贴片都通过馈电探针直接端接负载时,阵列的散射场峰值和能量都有所减小;而阵列通过馈电网络进行馈电时,馈电网络末端有无端接负...

| Abstract: | For the microstrip patch antenna array,the influences of feeding networks constructed by probes and microstrips on the back-scattered field are analyzed using finite-difference time domain(FDTD)method in this paper when the incident pulse is polarized in horizontal and vertical directions respectively.The time domain waveform and the corresponding spectrum of scattered field are given.It shows that the peak value and energy of scattered field of the microstrip antenna array can be reduced if the patches are... |
