摘要： A Colpitts oscillator has an integrated circuit. The integrated circuit includes a transistor having an equivalent large size, a bypass capacitor connected between a collector of the transistor and a ground, a first feedback capacitor connected between a base and an emitter of the transistor, a second feedback capacitor connected between the emitter of the transistor and the ground, and an emitter follower connected to the emitter of the transistor. In a package, a stray reactance and a bonding wire are designed so as to agree with an element value and a Q value which can be used as parts of a resonator. A surface elastic wave resonator disposed outside the integrated circuit is connected between the base of the transistor and the ground. The oscillator is voltage controlled by a variable capacitance diode connected in series with the resonator.

摘要： A hemispherical dielectric resonator is arranged on a conductive substrate with a flat surface of the resonator in contact with the conductive substrate and fixed by a pair of fixing blocks. The dielectric resonator is fed with a signal feeder at a position at one side of the resonator such that intensity of the electric field is higher at that position. The fixing blocks contact a portion of the dielectric resonator where the intensity of the electric field is of a local minimum.

摘要： A strip dual mode loop resonator includes loop-shaped strip line having a pair of straight strip lines arranged in parallel, an electric length of the loop-shaped strip line being equivalent to a wavelength of a microwave circulated in the loop-shaped strip line in two different directions according to a characteristic impedance of the loop-shaped strip line, and the straight strip lines being coupled to each other in electromagnetic coupling to change the characteristic impedance of the loop-shaped strip line. The microwave is transferred from an input strip line to the loop-shaped strip line through electromagnetic field induced by the microwave. Thereafter, the microwave is reflected in the straight strip lines of the loop-shaped strip line to produce reflected microwaves circulated in opposite directions. Thereafter, the reflected waves are resonated and filtered in dual mode in the loop-shaped strip line. Thereafter, the microwave formed of the reflected waves is transferred from the loop-shaped strip line to an output strip line through electromagnetic field induced by the microwave.

摘要： A hemispherical dielectric resonator is arranged on a metal substrate to make a flat surface of the hemispherical dielectric resonator contact with the metal substrate, and a dielectric wave-guiding channel is connected with a curved side surface of the hemispherical dielectric resonator. Therefore, a dielectric resonance antenna in which the hemispherical dielectric resonator and the dielectric wave-guiding channel are placed on the same metal substrate is obtained. A signal transmitting through the dielectric wave-guiding channel is fed in the hemispherical dielectric resonator, the hemispherical dielectric resonator is resonated, and an electromagnetic wave is radiated. Therefore, the dielectric resonance antenna functions as a wave radiation device.
