摘要
平面单极性天线可用来提供很高的的阻抗带宽特性,应用于目前或将来的宽带系统中.采用三维时域有限差分法(FDTD)对平面单极性天线周围空间的电场及磁场的分布进行可视化计算,并计算出该天线在不同频率下的输入阻抗和反射损耗,从而得到天线的工作带宽,以验证设计原理.
The planar monopole antenna provides extremely high width impedance characteristics which has been proposed for modern and future wideband wireless applications.In the present work by using the three-dimension finite-difference time-domain (FDTD) method, the visible calculation of the distribution of electric and magnetic field around the antenna is performed, meanwhile the input impedance and return loss of the antenna are also calculated. Thus the impedance bandwidth of the antenna is obtained.
