Abstract

An approach to microstrip antennas is developed that is based on a mixed transient-frequency analysis. The solution of transient integral equations by the method of moments allows one to compute the transient currents on the antenna. The Fourier transform of these transient currents used in asymptotic expressions for the far field of a Hertz dipole leads directly to harmonic parameters of radiation. The relative importance of spherical space waves and cylindrical surface waves and their behavior in terms of substrate parameters and frequency are discussed for some cases
