摘要： A directional coupler includes two non-radiative dielectric lines, each formed by a dielectric strip between flat conductive surfaces placed substantially parallel to each other, such that the two non-radiative dielectric lines are close to each other. The main transmission mode of electromagnetic waves at the frequency used is an LSE mode, the electromagnetic waves being propagated in the non-radiative dielectric lines. Therefore, the insertion loss due to mode switching in the coupling portion of the primary line and the secondary line which form the directional coupler can be reduced, and leakage of the electromagnetic waves from the gap between the primary line and the secondary line of the directional coupler when they are separated from each other can be suppressed.

摘要： A sector antenna apparatus mounted on a vehicle has a casing, in which six horn antennas having apertures over an angular range of 180 degrees and extending radially are accommodated. The proximal ends of the horn antennas are connected to an antenna changeover switch. A portion of the horn antennas which emits beam radiation in the forward and backward direction and diagonal direction of the vehicle have large apertures, and a portion of the horn antennas which emits beam radiation to the right and left of the vehicle have a small aperture. Thus, the required antenna characteristics, such as angular resolution, beam width, antenna gain, are achievable in the required direction.

摘要： A phase shifter includes upper and lower conductive plates, and a dielectric strip sandwiched between the conductive plates, and a plurality of slots formed in the upper conductive plate, thereby forming a dielectric line. A rotator is positioned at either side of the dielectric strip so that the distance from the rotator to the dielectric strip varies as the rotator rotates. As the rotator rotates, the phase constant of the dielectric line progressively changes in the direction of electromagnetic propagation. The rotation of the rotator causes a change in feed phase with respect to the slots as the rotator rotates, thereby performing beam scanning.

摘要： A dielectric filter includes a case, a substrate having microstrip lines formed thereon, and a dielectric plate having non-electrode parts serving as dielectric resonators. The case includes a supporting part for supporting the lower surface of the dielectric plate and includes a side wall surrounding the side faces of the dielectric plate wherein the supporting part and the side wall are formed in an integral fashion. The substrate is bonded to the case and the dielectric plate is mounted on the supporting part of the case. A metal cover is then placed on the case such that the opening of the case is closed with the cover. In the dielectric filter constructed in the above-described manner, warping of the case for supporting the dielectric plate is suppressed and thus the stress exerted on the dielectric plate is reduced. As a result, the dielectric plate is prevented from being separated from the case and also prevented from having a crack. The above-described structure also allows the dielectric filter to be formed into a small size. The invention also provides a duplexer and a communication device using such a dielectric filter.

摘要： A dielectric filter comprises a cubic dielectric block in which a plurality of holes arranged in the longitudinal direction are formed vertically therethrough. On outer surfaces of the dielectric block, an outer conductor is formed except on the upper surface. On inner surfaces of a plurality of the holes, inner conductors constituting resonance elements in cooperation with the outer conductor are formed. Grooves are formed in the dielectric block between the adjacent resonance elements. Thereby, impedance of a part of a lengthwise direction of at least one of the adjacent resonance elements differs from that of the other part, at least in one of the even and odd modes. In order to have different impedances, notches may be formed on the dielectric block between the adjacent inner conductors or large and small diameter portions may be formed in the holes or further the two methods may be combined.
