摘要： A planar antenna is disclosed. The planar antenna includes: a radiator element having a wideband resonant characteristic; and a parasitic element having a planar shape. The parasitic element has a first side, a second side, a third side and a fourth side. Each of the first side and the second side is parallel to a direction of an electric current to be excited in the radiator element. The first side is located closer to the radiator element than the second side is. The first side is shorter than the second side. The third side connects one ends of the first side and the second side. The fourth side connects the other ends of the first side and the second side. A region between the third and fourth sides tapers in a direction from the second side toward the first side.

摘要： An antenna system for use in a wide frequency band has a reflection board that has a board shape with an outer edge and an inner edge. The antenna system connects the reflection board and an antenna module in a manner that does not allow a flow of a direct current. Further, a dimension of the reflection board along a polarization direction of the antenna module has a value that is equal to or greater than a product of a maximum wavelength of a usable frequency band multiplied by a wavelength reduction rate of a dielectric material.

摘要： An antenna module includes a substrate; a ground element disposed on the substrate; a first antenna element disposed on the substrate; and a second antenna element disposed on the substrate. The first antenna element and the second antenna element are, respectively, capable of transmitting radio waves having a first polarization direction and a second polarization direction unparallel to each other. A spacing between a perimeter of the ground element and the first antenna element increases as a function of increasing distance from the second antenna element. A spacing between the perimeter of the ground element and the second antenna element increases as a function of increasing distance from the first antenna element.

摘要： A vehicular communication device switches over a communication method between the OFDM method and the SS method. A PLC master set includes a LAN communication unit for performing data communications with control units such as an engine control ECU via an in-vehicle LAN. In the PLC master set, a microcomputer acquires the operating states of parts of the vehicle from various control units through the LAN communication unit, and uses the acquired operating states and control information stored previously to enable data communications without being affected by noises occurring in the parts of the vehicle by notifying a PLC slave set of a communication method in the PLC communication unit and a communication method with a sub-carrier set prohibited from use being set when a communication method is the OFDM method.
