摘要： A grommet is provided with a small diameter tube portion which receives a wire harness therein in a fitted condition, and is provided with an enlarged diameter tube portion which continues in a generally conical tube shape from one end of the small diameter tube portion. A recessed portion for hooking on an automobile body panel is provided on an outer peripheral surface of the enlarged diameter tube portion. The height of first and second peripheral side walls on opposite sides of the bottom surface of the recessed portion is established so that the height of the second side wall of the small diameter tube portion side in the opposite side is about 50% to 35% of the height of the first side wall of the opening end side of the enlarged diameter tube portion side. Furthermore, the width dimension of the recessed portion between the first side wall and second side wall is greater than the height dimension of the second side wall, and the second side wall deforms inwardly into the recessed portion. Thus, the grommet can be easily installed in a single push-in motion of the grommet into the penetration hole of the automobile body panel.

摘要： A grommet is fit externally to a wire harness to be wired in a vehicle and mounted in a through hole of a vehicle-body panel. The grommet has a small-diameter cylindrical portion molded of elastomer and through which the wire harness is tightly inserted. A radial projection in the form of bellows projects radially out from an outer peripheral position of an intermediate longitudinal part of the small-diameter portion. An outer peripheral portion is connected to the outer peripheral end of the radial projection. The outer peripheral portion has a conical tubular shape and is connected at an intermediate longitudinal position to the radial projection. An annular vehicle-body locking recess is provided on the outer peripheral surface of a large-diameter side of the outer peripheral portion. A small-diameter side is thicker than the radial projection portion.

摘要： An antenna apparatus includes a slit provided on an antenna element between first and second feed ports; and a series resonant circuit provided at a location along the slit, with a distance from an opening of the slit. When the antenna apparatus operates at a first isolation frequency identical to a resonance frequency of the series resonant circuit, the series resonant circuit is short-circuited, and only a section of the slit from its opening to the series resonant circuit resonates, thus providing isolation between the feed ports at the first isolation frequency. When the antenna apparatus operates at a second isolation frequency lower than the first isolation frequency, the series resonant circuit is open, and the entire slit resonates, thus providing isolation between the feed ports at the second isolation frequency.

摘要： An antenna element has first and second feed ports, and is simultaneously excited through the feed ports so as to simultaneously operate as first and second antenna portions respectively, associated with the feed ports. The antenna element is excited at one of a first frequency and a second frequency higher than the first frequency. An antenna apparatus is provided with: a slit that provides isolation between the feed ports; a trap circuit that allows the slit to provide isolation at the first or second frequency when the antenna element is excited at the first or second frequency; and a reactance element that shifts a frequency at which the slit provides isolation between the feed ports, to the first frequency, when the antenna element is excited at the first frequency.

摘要： An antenna evaluation apparatus includes receiving antennas to be evaluated, scatterer antennas surrounding the receiving antennas, a signal generator, a divider, a phase-shift circuit, and a computer. The computer generates first and second initial phase vectors each corresponding to a different set of multipath waves, determines a third initial phase vector including arbitrary initial phases each between a pair of corresponding initial phases in the first and second initial phase vectors, adjusts the phases of the radio frequency signals using the phase-shift circuit such that the phases of the radio frequency signals have corresponding initial phases in the third initial phase vector, and makes the adjusted radio frequency signals radiate.

摘要： When a grommet provided with a wire insertion tubular portion is mounted in a through-hole of a vehicle body panel by engaging a vehicle body engagement recess on an outer periphery of the grommet with a peripheral edge of the through-hole, the present invention prevents the wire insertion tubular portion from being caught by the peripheral edge of the through-hole, bending toward the vehicle body engagement recess side, and being wedged in between the peripheral edge of the through-hole and the vehicle body engagement recess, and thus enables the grommet to be securely mounted in the through-hole. A rib is provided between an outer peripheral surface on a central axis line side of a wire insertion tubular portion and a peripheral wall of a central tubular portion in order to reinforce a base on the central axis line side of the wire insertion tubular portion.
