Abstract

PURPOSE: To stabilize the resonance properties by narrowing the width of the microstrip line at the coupling area to the dielectric resonator.
CONSTITUTION: With use of the substrate of a low dielectric constant, such as the Teflon substrate, the width of the strip conductor is increased to reduce the coupling force to the dielectric resonator. To avoid this, the width of strip conductor 27 on Teflon substrate 26 is narrowed at the coupling area to dielectric resonator 31 to increase the impedance. As a result, electric field 29 is extended between conductor 27 and earth conductor 28, and accordingly magnetic field 30 crossing vertically field 29 is also extended to secure coupling to resonator 31. Thus the strong coupling force can be obtained even for the resonator featuring a large height. In this way, the oscillation stoppage, the abnormal oscillation and the like can be avoided to obtain the steady oscillation properties.
