摘要： An amplifying circuit is formed by a combination of a dielectric line waveguide and a semiconductor device. Two electrically conductive plates are provided substantially parallel to each other. Two dielectric strips are disposed between the two conductive plates, and a dielectric plate is further inserted between the dielectric strips. Ground conductors are formed on the dielectric plate. The ground conductors have an area which equals an amount required for blocking a RF signal propagating in the dielectric line waveguide. A slot line is formed between the ground conductors in a position intermediate opposed sides of the dielectric strips. Line-switching conductor patterns are provided at both sides of the ends of the slot line. A field-effect transistor is mounted on the slot line such that it bridges over the slot line. Accordingly, losses and distortion of an RF signal, which would occur in an input/output circuit, are suppressed, and the generation of parasitic coupling is eliminated. Further, the dielectric line waveguide is miniaturized free from an external circuit, and accordingly, the manufacturing cost is reduced as well.

摘要： A high-frequency circuit device includes a substrate and a high-frequency circuit. The high-frequency circuit is provided on the substrate and has a signal line. The signal line is configured with a slot line provided by electrodes that are arranged side-by-side with a space therebetween on the substrate. The slot line can facilitates circuit design compared to a microstrip line and has significantly low conduction loss compared to a coplanar line, and can improve the Q-value of the high frequency circuit. This can provide an improved high-frequency circuit device having small phase noise. The high-frequency circuit device, which also serves as an oscillator, employs a slot output and thus can provide an advantage of better continuity for a class-B push-pull amplifier that operates more efficiently than a class-A one.

As an embodiment of the invention, a plurality of dielectric lines and a plurality of primary radiators are provided on a rotary unit. With the rotation of the rotary unit, the dielectric lines are switched ON and OFF by virtue of mechanical means, so that a desired change-over may be effected among the plurality of primary radiators in a time sharing manner, and the positions of the primary radiators may be shifted within a plane of the focal point of a dielectric lens, thereby enabling the transmission wave beam and/or reception wave beam to scan in a desired manner.

摘要： The invention provides an antenna in which a signal is directly transferred from a planar dielectric transmission line to a primary radiator without having to perform transmission mode conversion from the planar dielectric transmission mode to another mode such as a coplanar transmission mode, a microstrip transmission mode, or a waveguide transmission mode thereby eliminating the transmission loss which would otherwise occur due to the transmission mode conversion. A dielectric resonator is disposed in the vicinity of the end of the planar dielectric transmission line PDTL formed between two slots disposed on both sides of a dielectric plate. Furthermore, a slotted plate, a lens supporting base, and a dielectric lens are disposed one on another.

摘要： A planar dielectric line having a first slot sandwiched between first and second electrodes is provided on a surface of a dielectric substrate. A second slot is positioned so as to face the first slot and is sandwiched between third and fourth electrodes on the rear face of the dielectric substrate. The width of the first slot is narrower than the width of the second slot so that the electromagnetic field energy of a high-frequency signal is concentrated in the first slot.
