✦ Synopsis

sity from 0.35 Wb/m2 to 0.4 Wb/m2, which is shown in Figure 3. The variation of resonant frequency with angle of inclination for different values of dc magnetic field is shown in Figure 4. The angle of inclination is varied from 0 to 30°, with dc magnetic field poHo of 0.35 to 0.4 Wb/m2. Thus, from these results it is inferred that the tuning can be achieved by varying the inclination angle of the magnetic field or by varying the magnetic field intensity for a fixed angle of inclination

IV. CONCLUSION

A tunable filter with a microstrip ring resonator configuration on YIG-GGG substrate has been proposed, and the results are obtained by deriving its equivalent network model. Sharp notch characteristics of more than 40 dB have been observed at X band, and the results may be useful for magnetostatic wave application to filters at microwave frequencies.
