The Optimum Design of PIFA Based on HFSS and Genetic Algorithm

摘要

In this paper we demonstrate the optimization of planar inverted F antenna (PIFA) for broadband operation by optimizing the geometry/size of the inverted-F patch and the position of the shorting pin. The optimization technique based on the combination of Genetic Algorithm(GA) with HFSS is presented to facilitate the PIFA design. The technique is compiled by Matlab and the VB scrip of HFSS. The simulation results show that the method broadens the bandwidth of the PIFA antenna.
