Abstract

The validity of the leaky cavity and transmission-line models to predict the far zone fields from a microstrip patch antenna is investigated. The prediction of this radiation requires a knowledge of the total current on the antenna. Since the approximate techniques utilise only the current on the bottom surface of the antenna, the relative importance of top and bottom surface currents are examined.
