摘要

随着计算机能力的不断提高，求解辐射问题的数值算法也在不断发展，时域有限差分法(FDTD)在简化复杂的辐射问题方面展示了它的能力。本研究采用时域有限差分(FDTD)方法，在合适的吸收边界条件(ABC)和馈电模型下，利用不同形状的天线和不同类型的馈电信号(包括瞬态信号)，解决了二维(2D)和三维(3D)介质谐振器天线(DRA)问题。得到了这些情况下的电场强度和辐射方向图。

Finite difference time domain solutions for the dielectric resonator antenna problems with different feeding signals

With the great growth continuing in computers' power that is associated with a big growth in the numerical algorithms for solving radiation problems, the finite difference time domain (FDTD) method has taken its chance to demonstrate its power in simplifying the sophisticated radiation problems. In this research, the FDTD method is used, with suitable absorbing boundary conditions (ABC) and feeding model, to solve the dielectric resonator antenna (DRA) problems both in two dimensions (2D) and three dimensions (3D) using different shapes of the antennas and different types of the feeding signals including transient signals. The resultant electric field strengths and radiation patterns are obtained for these cases.
