Jh. Lee et Jw. Ra, FULL-WAVE CALCULATION OF THE RADIATION IMPEDANCE OF MICROSTRIP-EXCITED MAGNETIC SURFACE-WAVES, Microwave and optical technology letters, 6(7), 1993, pp. 441-444
The radiation impedance of a microstrip having ferrite film and its de
pendence on the width of the microstrip and the height of the ferrite
film are calculated by the full-wave moment analysis. Full-wave calcul
ations closely predict the measured radiation resistance, while the ma
gnetostatic approximation deviates in the higher-frequency region.
