Modelling of bow-tie microstrip antennas usingmodified locally conformal FDTD method

Abstract

An analysis of bow-tie microstrip antennas is presented based on the use of the modified locally conformal finite-difference time-domain (FDTD) method. This approach enables the number of cells along the antenna length and width to be chosen independently of the antenna central width, which helps to keep the number of cells required in those directions to a minimum. The analysis results are compared with experimental results and good agreement is observed
