radial stub has been presented. Although the curvilinear FDTD gives quite accurate results, it leads to larger computer requirements than a simpler staircasing approximation. Indeed, depending on the geometry of the metallizations, the mesh constraints can be a serious limitation. The method is more

β¦ Synopsis
A new time-domain technique for determining the radiation Q of an antenna is presented. The time integral of power returning to the antenna from the standing energy field upon source turn off is determined numerically, and is used as a measure of the peak standing energy for Q determination.
