Abstract
The radiation impedance of a magnetostatic surface wave excited in a microstrip line haying ferrite film and its dependence on the width of the microstrip line and the height of the ferrite film are calculated by the full-wave moment analysis. The radiation resistance calculated by the full-wave analysis closely agrees with the measured radiation resistance, while that by the magnetostatic approximation greatly differs from the measured result in the higher-frequency region.
