摘要： In a conventional automotive radar, a return occurs in a phase difference characteristic necessary for a super-resolution method, resulting in an increase of a detection error, or an extremely narrowed azimuth detection range. A transmitting array antenna, and receiving array antennas are composed of antenna elements respectively, and aligned in a horizontal direction. The weighting of receiving sensitivities of the antenna elements of the receiving array antenna 1 is A1, A2, A3, and A4, which are monotonically decreased from an inner side toward an outer side as represented by A1≧A2≧A3≧A4. On the other hand, the receiving array antenna 3 is symmetrical with the receiving array antenna with respect to the receiving array antenna 1.

摘要： In a millimeter waveband transceiver using an antenna and a waveguide for a connection line, it is necessary to perform transmission mode line conversion between TEM waves of a microstrip line and VTE01 mode waves of the waveguide. There is a limit to reducing the conversion loss using only a matching box for connecting the microstrip line with the waveguide. In a transmission mode line transducer for converting between the TEM waves of the microstrip line and the VTE01 mode waves of the waveguide, if the cross-sections are substantially the same size, in the case of a 50Ω microstrip line when the characteristic impedance of the waveguide is about 80%, i.e., 40Ω, the line conversion loss can be optimized. Therefore, the microstrip line is connected with the waveguide using a λ/4 matching box via a ridged waveguide having a low impedance and a length of λ/16 or less.

摘要： An electromagnetic wave propagation medium 1 extends in the propagation direction of an electromagnetic wave and has an electromagnetic wave propagation space sandwiched between conductors in the direction perpendicular to the electromagnetic wave propagation direction. A base unit 2 and multiple terminals 3 are placed on the electromagnetic wave propagation medium 1. When the position of a terminal 3 is detected, the base unit 2 transmits a position detection signal through the electromagnetic wave propagation medium 1 to the terminal 3. This position detection signal is attenuated more heavily during its propagation through the electromagnetic wave propagation medium 1 than a communication signal for use in normal communication is. The signal strength of the position detection signal drops as it moves away from the base unit 2. Hence the position of each terminal 3 can be detected based on the signal strength of the position detection signal received by each terminal 3.
