摘要： In an antenna, a first element is connected to a GND of a feeder, on the same plane as a GND of a wireless circuit, and isolated from the GND of the wireless circuit. A second element is on the same plane as the GND of the wireless circuit and a first end connected to the first element and a second end as an open end. The third element has a first end connected to a power source of the feeder and located in a region occupied by the first element perpendicularly to the first element so that its first end source faces down. The fourth element has a first end connected to a second end of the third element and a second end as an open end, is parallel to the first element, and is perpendicular to a line connecting the first and second ends of the second element.

摘要： In a smart system, an onboard system transmits a request signal. A portable device receives the request signal. An LF demodulation portion demodulates the request signal to acquire request data and returns an answer signal based on acquisition of the request data. The onboard system receives the answer signal and performs smart drive based on reception of the answer signal. The onboard system also transmits a specified counter-RA signal. A switching circuit of the portable device outputs the received counter-RA signal to a modulation portion while bypassing the LF demodulation portion. The modulation portion performs RF modulation using the counter-RA signal to acquire a counter-RA modulation signal and transmits the counter-RA modulation signal. When receiving the counter-RA modulation signal, the onboard system determines whether to allow or disallow the smart drive based on delay time of timing to receive the counter-RA modulation signal with reference to timing to transmit the counter-RA signal. This enables to suppress variations in the transmission/reception delay time inherent in the smart system.

摘要： A vehicle system includes a vehicle-mounted device mounted to a vehicle and a portable device portable by a user, and performs a control to the vehicle corresponding to a collation result performed based on a wireless communication established between the vehicle-mounted device and the portable device. The vehicle-mounted device includes a vehicle-mounted transmission unit which simultaneously transmits radio waves having a predetermined phase difference using at least two transmission antennas disposed orthogonal to each other. The portable device includes a triaxial reception antenna receiving the at least two radio waves, and a magnetic field strength detection unit detecting a magnetic field strength on each of three axes of the triaxial reception antenna. One of the vehicle-mounted device or the portable device includes an illicitness determination unit determining, based on the detected magnetic field strength, whether the wireless communication is established through an illicit repeater.

摘要： A first communication apparatus and a second communication apparatus are capable of wireless communication with each other. The first communication apparatus has a normal operation mode and a tuning mode that differs from the normal operation mode and allows a variable matching portion to adjust a matching state. When the tuning mode is selected, the first transmission portion transmits an operation mode transition request signal to the second communication apparatus. A first reception portion receives a tuning reference signal transmitted from the second communication apparatus in response to the operation mode transition request signal. A reception signal intensity measurement portion measures a reception signal intensity of the received tuning reference signal. The variable matching portion adjusts a matching state based on the measured reception signal intensity of the tuning reference signal.

摘要： A reception strength detection unit is connected to reception antennas located in a vehicle compartment and detects a reception strength of a radio wave from a mobile terminal for each of the reception antennas. A reception determination unit is connected to an auxiliary antenna located at a predetermined position that is a blind spot of the reception antenna and determines whether the radio waves has been received by the auxiliary antenna. When the radio wave has not been received by the auxiliary antenna, an existence position calculation unit calculates an existence position of the mobile terminal based on the reception strength detected by the multiple reception antennas. When the radio wave is received by the auxiliary antenna, the existence position determination unit determines the predetermined position at which the auxiliary antenna receiving the radio wave is located as the existence position of the mobile terminal.
