We have developed a rear spoiler with built-in antenna. The spoiler has two features. First, the built-in antenna does not protrude from the vehicle contour and has an improved serviceability. Second, the air flow effect provides the driver with a clearer rear view, resulting in an improved safety. This paper discusses characteristics of the rear spoiler with built-in antenna.

In order to evaluate the toughness of automotive ECU's to electrostatic discharge, a conventional method where electrostatic discharge pulse is applied to connector parts on a printed circuit board is commonly used. But quantitative re-designing principles to improve the static electricity tolerance have not been made clear that completely utilizes the test data shown below till now, because propagation mechanism of static electricity on a circuit board is not clear. This paper describes the ESD current measurement technique which detects the near magnetic field generated by ESD currents. We developed to measure the ESD currents using the new loop antenna on a circuit board. The ESD current, was generated with the static electricity applied to a model circuit pattern in conformity with IEC and ISO standard and measured using the antenna. Also it was able to visualize how static electricity energy would propagate through the circuit board.

In recent years the number of vehicles equipped with millimeter wave radar has been increasing due to the popularization of driving assistance systems such as adaptive cruise control (ACC) and forward vehicle collision warning (FCW) systems. Consequently, high performance millimeter wave radar must be developed to support even more advanced driving assistance systems. The investigation described in this paper confirms that it is possible to use high range resolution radar to recognize the width of a target. In tests, a simulated radar signal was transmitted and received by a millimeter waveband network analyzer using a 1.6 meter-wide aluminum foil board as the target. When the range resolution was low, only one point of reflection from the board could be detected. However, when the range resolution was improved, then multiple points of reflection from the target could be detected.
