✦ Synopsis
An efficient FDTD approach, which uses the modified ( ) locally conformal finite-difference time-domain method MCFDTD and the concept of symmetry plane, for the analysis of center-fed bow-tie microstrip antennas is presented. The use of MCFDTD enables us to choose the number of cells along the antenna length and width independent of the antenna central width, and the concept of symmetry plane helps us reduce the problem space size to exactly half of the otherwise required size. The simulation results are compared with experimental results to check the accuracy and suitability of the method, and good agreement is found.
