First, we deduce theoretical formulae of calculating equivalent dielectric constant and resonance frequency of rectangular microstrip antennas with air gaps from electromagnetic field theory based on the modified theory of cavity model. Then, we discusses the radiant principle of microstrip antennas on the base of transmission line theory and analyzes the problem of air gaps how to influence pattern and other idiocratic parameters of a microstrip antenna in detail.
