Abstract
We present a FDTD algorithm to model the near-field radiation characteristics
of dipole antennas. The antenna is represented as a wire with a small
gap in the middle. The initial condition is given by a time-variable
voltage pulse fed into the central gap in the wire. The resulting
E-field in the gap can be calculated analytically, whereas the E-
and H-fields in the icinity of the wire are evaluated by numerical
solution of an integral representation of Maxwell's equations. Integration
contours and surfaces are defined by the cells surrounding the wire.
