摘要

The radiation pattern, input impedance and resonance frequency of a ring-slot antenna are derived and compared with measured results. The analysis is based on the transmission-line model and an assumed electric field in the slot region. Initially, the model of a ring-slot in an infinite ground plane is developed and then the effect of the ground plane is added by geometrical theory of diffraction (GTD) techniques. Theoretical results are in good agreement with experiment.
