摘要： A thin film capacitor includes a pair of electrodes and a dielectric layer having piezoelectricity sandwiched therebetween. The phase characteristic of an impedance resulting from application of a voltage to the pair of electrodes peaks periodically according to a frequency of a signal to be inputted or outputted. The frequency of the signal is adjusted to fall in between the values representing the adjacent peaks. Since there are periodic peak values that depend upon the frequency of the inputted or outputted signal, in fabricating a band-pass filter, a higher attenuation can be attained by ensuring that the peak value stands at a low-frequency level. Thus, a higher attenuation can be attained at low frequencies without sacrificing the band-pass characteristic, whereby making it possible to produce a band-pass filter that is excellent in band-pass characteristic.

摘要： A module equipped with a non-radiative dielectric waveguide in accordance with this invention comprises a pair of parallel flat conductors arranged at a space of 1/2 or below of a high frequency signal wavelength .lambda. and a dielectric strip extending between these parallel flat conductors. This dielectric strip is formed from a cordierite ceramic having a dielectric constant of 4.5 to 8, especially 4.5 to 6. Conversion of an electromagnetic wave of LSM mode to an electromagnetic wave of LSE is minimal. When the module has a dielectric strip having a steep curved portion having a small radius of curvature, the transmission is possible with a low loss, and the band width of a high frequency signal is broad.

摘要： A non-radiative dielectric waveguide coupler for coupling or dividing high-frequency signals between at least two dielectric waveguides arranged maintaining a predetermined gap between a pair of parallel flat conductors, wherein said two dielectric waveguides are connected to each other through a bridge of a dielectric material. Upon joining the two dielectric waveguides through the bridge, the gap between the two dielectric waveguides, that affects the characteristics of the coupler, is set maintaining a high precision without effecting any particular positioning operation. Therefore, the coupler can be mass-produced very favorably. Besides, the gap between the two dielectric waveguides is stably maintained without being varied during the production of the coupler or during the use of the coupler, contributing to improving the reliability of the coupler. A drop in the characteristics of the coupler stemming from the provision of the bridge is easily avoided by setting the width of the bridge to be smaller than the width of the dielectric waveguides.

摘要： The invention relates to a small and low-voltage operable dielectric waveguide device. First and second electrode are embedded in a dielectric part and are formed to be thinner than a skin depth for a frequency of electromagnetic wave propagating along a first dielectric part included in the dielectric part. Thereby, even if the first and second electrodes are arranged to be in contact with the first dielectric part, the propagating electromagnetic wave can transmit the first and second electrodes, and therefore the electromagnetic wave can propagate without being cut off and there is no influence on waveguide modes of the electromagnetic wave. Further, in a state where a transmission loss due to the embedded of the electrode is suppressed, an electric field with large electric field strength can be applied to the first dielectric part by the first and second electrodes, and a small and low-voltage operable dielectric waveguide device can be achieved.
