摘要： PROBLEM TO BE SOLVED: To provide a wiring structure of feeder for road-side antenna that can maintain a good communication quality, by suppressing an increase in effective resistance and the fluctuation of impedance, even if the wired lengths of feeders are long and the weather of ambient environment changes. SOLUTION: The feeders 8 from road-side antennas 2, composed of loop antennas buried in a reserved road A to transmitters-receivers 4 installed to a transmitter-receiver installation facility B, are wired through pipelines 6 laid at positions higher than the ground surface. Since the feeders 8 are always held in the atmosphere having a small specific inductive capacity, the distributed capacity in between the feeders 8 and, in its turn, the effective resistance of the impedance of the feeders 8 from the connected ends with the transmitters- receivers 4 to the antennas 2 can be suppressed to a small value. In addition, since the feeders 8 are not exposed directly to wind, rain, and snow, the large fluctuations of the impedance can be prevented.

摘要： PROBLEM TO BE SOLVED: To satisfactorily perform matching by suppressing an impedance increase in a roadside antenna even when the roadside antenna for communication between vehicle and road is installed in a section with a long communicable section length. SOLUTION: In this roadside antenna 1, one conductive loop made of a conductive line formed in a rectangular shape is divided into two small loops (loop antenna elements 11 and 12) with an intersecting point of the conductive lines by twisting the conductive loop at a center part in a longitudinal direction, and power feeding is parallelly performed to the respective small loops from one power feeding point in the vicinity of the intersecting point. It is possible to suppress the impedance of the roadside antenna lower than that of a loop antenna with the same coil length as that of the roadside antenna 1, singly structured as a roadside antenna by making the two small loops having a configuration that the small loops are adjacently arranged (electrically parallelly connected) in this way. It is therefore possible to satisfactorily match with a power feeding side. COPYRIGHT: (C)2003,JPO

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.
