Abstract :
The insertion loss for multibar magnetostatic-surface-wave (m.s.s.w.) transducers has been calculated from a `small¿-loss microstrip-transmission-line model. Experimental results for 2-bar and 8-bar parallel-strip and 4-bar ¿ transducers are in excellent agreement with theoretical predictions. The 8-bar parallel-strip-transducer delay line gives a major bandpass response at 3.1 GHz, corresponding to an m.s.s.w. wavelength of 300 ¿m. The insertion loss is 11 dB, the 10 dB bandwidth is 70 MHz and adjacent sidelobes are 16 dB down.
