Abstract
The transmission-line modelling (TLM) method has been successfully app lied to compute many open boundary problems, such as current distribut ion on antennas and antenna radiation patterns. The method is Further exploited to calculate the impedance of dipole antennas. A good agreem ent with the moment solution has been obtained over a wide frequency r ange. However, it was observed that the method is less accurate at low frequencies. Possible explanations are given for this shortcoming.
