Abstract
In this paper, a staked microntrip antenna with a high gain is analyzed using the FDTD method. The staked microstrip antenna whose the parasitic element set at the hight of about a half wavelength from the fed element has high gain. The characteristics of antennas and electric and magnetic fields of around antennas can be calculated using the FDTD method. The gain radiation patterns and impedance of the staked microstrip antenna are analyzed. The near fields of the staked microstrip antenna are calculated to discuss the gain enhancement.
