Abstract
The finite-difference-time-domain (FDTD) method is used in an interact ive mode to improve the performance of a TEM horn antenna for pulse ra diation. The new design is shown to yield a small reflected voltage in the feeding transmission line, to radiate a far-zone field in the axi al direction that is proportional to the derivative of the incident vo ltage, and to be fairly directive. Experimental results are in very go od agreement with those predicted by the theory. (C) 1996 John Wiley & Sons, Inc.
