摘要： A speed sensor which aligns a normal direction of one patch antenna which is disposed on a mounted board, and an optical axis of a dielectric lens uses a frame for inclining a sensor module, in order to obtain a component cos θ in a traveling direction when the speed sensor is installed on a horizontally vertical surface of an automobile or a railway car. When beams are condensed by using the one patch antenna and the cannonball-shaped dielectric lens, the dielectric lens is inclined and a bottom surface portion of the lens is cut with a plane parallel with a surface of the antenna-mounted board. The one patch antenna is configured by one patch and a GND electrode and the gain center of radiation characteristics is a normal direction of the antenna board. However, the radiation characteristics have a substantially hemisphere surface wave shape.

摘要： A millimeter-wave antenna includes a slit which is provided in a GND conductor formed in a first surface of a circuit board, a horn antenna which is provided with a first opening and a second opening, and an impedance matching device which is provided in a slot shape between the slit and the first opening of the horn antenna. The impedance matching device is formed in the slot shape which is filled with a dielectric having a dielectric constant different from that of the circuit board. The impedance matching device is configured such that a length of the slot shape in a propagation direction is less than 1/4 of a wavelength of a use frequency upper limit. The impedance matching device is configured such that a size of a rectangular shape of the slot shape in a magnetic field direction is larger than the first opening of the horn antenna.

摘要： A sensor has an antenna. The antenna includes a radiation source and a wave guide. The radiation source is formed on a substrate. The wave guide internally propagates electromagnetic waves radiated from the radiation source and radiates the electromagnetic waves as a beam. The wave guide has a radiation-side opening in which a first direction and a second direction are orthogonal to each other, and the second direction is longer than the first direction. In a cross-sectional shape of the beam, perpendicular to a radiation direction of the beam radiated from the wave guide, a first direction and a second direction are orthogonal to each other, and the second direction is narrower than the first direction.
