The Use of Three Dimensional Finite Difference Time Domain Method for Multiband Antenna Analysis

Amel Boufrioua, Meriem Harbadji

Abstract


This paper presents an effective design of multiband patch antenna. The proposed antenna can be designed for dual band, triple band and multiband applications by using U-shaped form for the patch. The results in terms of return loss are given. It is observed that various antenna parameters are obtained as a function of frequency for different value of slot length and width; also it is found that the separation of the upper and the lower resonances is controllable with these dimensions. Moreover the dual or multiple resonances can be achieved by the choice of specific substrate and by varying the different U shaped parameters, which gives the antenna the property of dual and multiband operation to be used for several applications. Our results were studied with the aid of FDTD numerical analysis. The microstrip line is used to excite this new antenna.

Keywords: dual frequency, FDTD method, multiband, patch antenna
