The present invention provides a method for adjusting the frequency of an oscillator. The method comprises providing a substrate having a plurality of openings, forming a conductive layer on a first surface of the substrate and patterning the conductive layer to form a plurality of strip line, one of which is formed corresponding to the openings to become an inductance circuit, covering the conductive layer with a lid, and cutting part of the strip line through the plurality of openings from the opposite side of the first surface to adjust frequencies of the oscillator.
