摘要： PROBLEM TO BE SOLVED: To improve receiving performance of a vehicular radio wave receiver. SOLUTION: A wiring board 2 having a receiving circuit 20 formed thereon is arranged so that a ground pattern 22 is arranged by closely facing the rear face 41a of a roof panel 41 so as to be closer to the edge of a rear window 51. A base end 301 of a rod-shaped dielectric antenna 3 for outputting a received signal to the receiving circuit 20 is positioned in a terminating part of the rear window 51 side of the wiring board 2, and the dielectric antenna 3 is extended toward the rear window 51. A roof panel 41 close to a ground pattern 22 is used as a preferable grounding through capacitive coupling with the ground pattern 22, and the dielectric antenna 3 is preferably formed into a monopole antenna. Moreover, the dielectric antenna 3 is extended toward the rear window 51, thereby inhibiting the dielectric antenna 3 from influenced by a metal-made member. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To simplify matrix arithmetic operation by a demodulation section of each finger in a receiver adopting the CDMA transmission system, where a plurality of fingers and combiners are provided to conduct RAKE synthesis. SOLUTION: This receiver, adopting the CDMA transmission system, uses correlation value signals ICOR, QCOR obtained by applying inverse spread processing to a baseband signal to decide a bit segmentation position from a correlation value signal by one slot, whose absolute value is a maximum so as to segment bits of the correlation value signal. A bit segmentation position is decided similarly even with respect to channel estimate value signals ACOS, ASIN from a channel infer section 205 to segment bits of the signals ACOS, ASIN. Then a demodulation section 208 conducts matrix arithmetic operation from correlation value signals ICOR'. QCOR' and channel infer value signals ACOS', ASIN' whose bits are segmented to obtain demodulated data ISYMB', QSYMB'.

摘要： PROBLEM TO BE SOLVED: To provide an inverted-F antenna that saves the labor and time for mounting and suppresses individual differences in antenna radiation characteristics.
SOLUTION: Cuts are formed to a metallic plate 100 except a bent 55a by grooves 120 and a cut piece 130 is formed. Bending the cut piece 130 at the bent 55a bends a ground late 62 from a bottom side 55 together a feeding plate 61 and a radiation plate 63. The radiation plate 63 is bent at an end of the ground plate 62 with the feeding plate 61 and the feeding plate 61 is bent at the end of the radiation plate 63. Thus, the mounting work between the ground plate 62 and the bottom side is eliminated, and since the ground plate 62 and the bottom side 55 are formed by bending, individual differences in antenna radiation characteristics can be suppressed.

摘要： PROBLEM TO BE SOLVED: To decrease the number of on-board antennas of an electronic key system for a vehicle. SOLUTION: An on-board machine S transmits a request signal taking an electromagnetic wave as a medium by the on-board transmitting antenna 12, an electronic key K measures the receiving field intensity C of the request signal, and a response signal showing the receiving field intensity C is transmitted taking the electromagnetic wave as a medium. The on-board machine S receives the response signal taking the electromagnetic wave as a medium by the on-board receiving antenna 13, and measures the receiving field intensity D of the response signal. An electronic key ECU 17 determines the position of the electronic key K by comparing the receiving field intensity D with the receiving field intensity C, and unlocking of the lock mechanism of the door corresponding to the determined position of the electronic key K is permitted. Thus, according to the receiving field intensity D and the receiving field intensity C, the position of the electronic key K can be determined so as to decrease the number of antennas.

摘要： PROBLEM TO BE SOLVED: To increase an operation distance over a wider range by decreasing dip points. SOLUTION: A keyless transmitter comprises: a 1st loop antenna 6 which is patterned and formed on the surface of a circuit board; and a 2nd loop antenna 13 which is perpendicular to the plane of the circuit board where the 1st loop antenna is formed. Polarized waves having two mutually orthogonal planes of polarization are outputted as transmission waves from those 1st and 2nd loop antennas 6 and 13. When the transmission waves having the two planes of polarization are thus outputted as the transmission waves, then even if one polarized wave does not reach a receiver side, the other polarized wave can arrive at the receiver side, thereby increasing an area wherein a keyless entry system functions. A dead spot can therefore be reduced and the operation distance can be made longer. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an automobile-to-automobile communication system allowing occupants of a vehicle to know the location of a traffic accident ahead, to see how many vehicles there are behind the vehicle where the accident has occurred. SOLUTION: An electronic control unit 3 of an automobile B, upon receiving an emergency signal from another automobile A, determines that an accident has occurred, and then adds an accident occurrence signal to a vehicle number obtained by adding 1 to the vehicle number of the emergency signal received (S220). The accident occurrence signals added are sent as emergency signals from an antenna through a Bluetooth wireless device at predetermined time intervals (S230). Thus, the emergency signals are relayed by the communication device of the automobile B and the vehicle numbers are added together at each relaying. The electronic control unit 3 of an automobile C, upon receiving the emergency signal received by the communication device of the automobile B (S200), lets the occupants know the location of the traffic accident, that is, how many vehicles there are behind the automobile where the accident has occurred (S210).

摘要： PROBLEM TO BE SOLVED: To improve isolation between a transmitting array antenna 16 and a receiving array antenna 17 in a radar system obstruction detecting equipment S for beind mounted on vehicle. SOLUTION: An arrangement direction of transmitting antenna element 160-167 is inclined clockwise by a prescribed angle θ to the vertical direction, so that directivity as the transmitting array antenna 16 can be set not only in the horizontal direction but also in the vertical direction. Transmission signals R1-R8 from the transmitting array antenna 16 can be transmitted in a direction distance from the receiving array antenna 17. As a result, the receiving antenna array 17 can be restrained from direct reception of transmission signals from the transmitting array antenna 16. COPYRIGHT: (C)2004,JPO
