Microstrip patch antennas analysis based on SFDTD algorithm

LI Min-quan,LIU Shuang-bing,ZHAO Jin (Key Laboratory of Intelligent Compution and Signal Processing of Ministry of Education;Key Laboratory of Opto-electronic Information Acquisition and Manipulation of Ministry of Education,Anhui University,Hefei 230039,China)  
Based on the Maxwell's equations,a high-order symplectic finite difference time domain schemes is constructed for Hamilton system,a formula of iterative algorithm is proposed.The return loss and input impedance of microstrip antenna be calculated using symplectic finite difference time domain method(SFDTD) and absorbing boundary condition.Calculating results have shown that the SFDTD method is accurate and effective.It is useful for small antenna design and electromagnetism calculation.
