ABSTRACT:
An oscillator employing a strip line of tri-plate structure as a resonant element comprising a substrate having a strip line electrode embedded therein and a pair of grounding electrodes opposed to each other with the strip line electrode therebetween, neither of the pair of grounding electrodes being exposed on an upper main surface of the substrate, an oscillation circuit portion provided on the upper main surface of the substrate, a capacitor electrode provided on the upper main surface of the substrate, the capacitor electrode being opposed to the embedded grounding electrode, wherein one end of the strip line electrode is connected to the capacitor electrode and the oscillation circuit portion through a first connecting electrode extending from the above one end of the strip line electrode to the upper main surface of the substrate and wherein the other end of the strip line electrode is connected to at least one of the pair of grounding electrodes through a second connecting electrode.
