A miniature variable-beam microwave antenna (1) comprises antenna conductors (100a, 100b), an EBG conductor (120), a variable reactance element (130), and an adjusting part (150). The EBG conductor (120) is connected to a grounded part (160) through the variable reactance element (130). The adjusting part (150) changes the apparent reactance of the EBG conductor (120) by changing the capacity of the variable reactance element (130). As the apparent reactance of the EBG conductor (120) changes, the directivity of the miniature variable-beam microwave antenna (1) also changes.

摘要:
In a power-loss reducing system, a transmitting unit causes a radar to transmit a measurement radio wave, and a power monitoring unit monitors power of the measurement radio wave transmitted from the radar through a cover while changing a positional relationship between the cover and the radar. An extracting unit extracts a value of the changed positional relationship between the cover and the radar based on a result of the monitoring of the power such that the extracted value of the positional relationship allows reduction of power loss of a radar wave transmitted, through the cover, from the radar located based on the extracted value of the positional relationship.

In a semiconductor device, re-wiring is provided on a circuit element formation region of a semiconductor substrate. A columnar electrode for connection with a circuit board is provided on the rewiring. A first insulating film is provided over the semiconductor substrate excluding a connection pad, and a ground potential layer connected to a ground potential is provided on an upper surface of the first insulating film. A re-wiring is provided over the ground potential layer with a second insulating film interposed. The ground potential layer serves as a barrier layer for preventing crosstalk between the re-wiring and circuit element formation region. A thin-film circuit element is provided on the second insulating film, and a second ground potential layer is provided as a second barrier layer over the thin-film circuit element with an insulating film interposed. Re-wiring is provided over the second ground potential layer.

The radar apparatus includes an antenna device including a transmitting antenna and a receiving antenna, a main body which generates a radar wave, transmits the radar wave from the transmitting antenna, and receives the radar wave reflected from an obstacle to be detected by the receiving antenna, and a cover member covering the main body and the antenna device on a side of a transmission direction of the radar wave and located out of contact with the main body and the antenna device. The cover member has a transmission portion allowing the radar wave to pass therethrough, a surface of the transmission portion facing the antenna device being inclined by an angle greater than 3 degrees with respect to an antenna surface of the receiving antenna.
