Abstract: An antenna device 1 has a dielectric substrate 2, a patch antenna 5 and electric power absorbing passive elements 21, 24 formed on a surface of the dielectric substrate. Each electric power absorbing passive element 21, 24 is formed between the patch antenna 5 and an edge portion in a polarized wave direction of the dielectric substrate 2. The electric power absorbing passive elements 21, 24 absorb a part of electric power received by the patch antenna 5. This makes it possible to suppress a surface current flowing to the edge portions of the dielectric substrate on a conductive plate (a front-surface conductor plate 3 or a back surface conductor plate 4) on the dielectric substrate.

Abstract: An antenna apparatus has an antenna unit. The antenna unit transmits or receives a probe wave made of an electromagnetic wave. A magnet is disposed at a location through which the probe wave to be received by the antenna unit passes. The magnet works to generate a magnetic field along a direction in which the probe wave propagates. A polarizing filter is arranged on an opposite side of a magnetic body to the antenna unit. This minimizes the interference between an emitted wave and a reflected wave created by a cover, such as a bumper, regardless of the configuration of the cover.

Abstract: A wireless communication apparatus includes multiple antennas, a receiver for performing diversity reception using the antennas, a transmitter, a selector circuit connected to the antennas, a divider, and a phase shifter. The divider is located in a transmission line which connects the selector circuit to the transmitter and distributes a signal outputted from the transmitter among the antennas during transmission. The phase shifter is located in at least one of multiple transmission lines, each of which connects the divider to a corresponding one of the antennas.

Abstract: An antenna apparatus includes a dielectric substrate, a ground plate, a patch antenna provided with a patch radiating element, and a plurality of EBGs (Electromagnetic Band Gaps). The EBGs are composed of patch-shaped patterns formed on a surface of the substrate and connecting conductors electrically connecting the patch-shaped patterns and the ground plate. Each EBG is arranged to provide an EBG absent region having no EBG on the surface of the substrate. The patch radiating element is arranged within the EBG absent region. The EBG absent region is formed such that distances (absent distances) in a dominant polarized wave direction changes into a plurality of types depending on the position on a vertical patch line, where the distances range, to the boundary of the region, from an arbitrary position on the virtual patch line which is perpendicular to the dominant polarized wave direction of the patch antenna.

Abstract: A vehicle-mounted antenna device includes a base, a board, a circuit section, and a housing. The base is mountable on a roof of a vehicle. The board has an antenna element section and is stood on the base. The circuit section is implemented on the board and serves as at least part of a wireless communication circuit electrically connected to the antenna element section. The housing is made of a resin material and forms a projection of an outer shape of the vehicle. The board and the circuit section are located in space formed by the base and the housing. A heat transfer path having a thermal conductivity higher than that of air is formed between the circuit section and the housing without passing the base.
