The Analysis of Stacked Microstrip Antenna with Wide Bandwidth using the FDTD Method

Abstract

In this paper, a staked microstrip antenna with a wide bandwidth is analyzed using the FDTD method. The staked microstrip antenna with a parasitic element stacked near the fed element has a wide bandwidth. The characteristics of antennas and electric and magnetic fields of around antennas can be calculated accurately using the FDTD method. The frequency characteristics of impedance, gain and radiation patterns of the staked microstrip antenna are analyzed. The near fields around the elements are calculated to investigate the wide-band performance.
