PROBLEM TO BE SOLVED: To provide a high frequency oscillation circuit with which an oscillation frequency can be adjusted with high accuracy over a wide range at low cost by attaching conductors or dielectrics for oscillation frequency adjustment at the different positions of a microstrip line. SOLUTION: By attaching the conductors to the microstrip line, a cross-sectional area is changed and an inductance component is fluctuated. When the inductance component is changed at the position of high magnetic field strength on a microstrip resonator, the influence upon a system is enlarged. Oppositely, at the position of low magnetic field strength, the influence is reduced so that fine adjustment can be performed. Conductor regist 7 is formed on the microstrip line resonator and conductor attaching windows 8, 9 and 10 are provided from the position of strong magnetic field to the position of weak magnetic field on the microstrip line 3. The conductors are attached through one of these conductor attaching windows 8, 9 and 10 at least onto the microstrip line 3 so that the oscillation frequency can be adjusted. |
