Abstract: A vehicular antenna includes a transmitting antenna element, a receiving antenna element, a coupling portion, and an adjusting portion. The transmitting antenna element transmits a radio wave as a transmission wave. The receiving antenna element receives a radio wave as a receiving wave. The coupling portion electromagnetically couples a transmitting line through which the transmission wave passes with a receiving line through which the receiving wave passes. The adjusting portion adjusts, within the coupling portion, a mutual coupling amount between the transmission wave in the transmitting line and the receiving wave in the receiving line. The adjusting portion further adjusts a phase of the transmission wave to be coupled with the receiving wave by the coupling portion.

Abstract: An antenna device includes a ground plate that is a plate-shaped conductor member, a patch portion that is a plate-shaped conductor member placed to be opposed to the ground plate with a predetermined distance therebetween, a short-circuit portion that is a conductor member electrically connecting together the patch portion and the ground plate, and an additional conductor that is a plate-shaped conductor member placed to be opposed to the patch portion with a predetermined distance therebetween. The additional conductor is placed on a side of the patch portion on which the ground plate is not placed. An inductance of the short-circuit portion, a capacitance formed by the ground plate and the patch portion, and a capacitance formed by the patch portion and the additional conductor are used to perform parallel resonance.

Abstract: An antenna device according to an aspect of the present disclosure includes a zeroth-order resonant antenna and a first-order resonant antenna. The zeroth-order resonant antenna includes a base plate, a platy radiation element, and a connection conductor connecting the base plate and the platy radiation element. The zeroth-order resonant antenna is configured to transmit and/or receive a first linearly polarized radio wave in all directions perpendicular to the first linearly polarized radio wave by zeroth order resonance. The first-order resonant antenna includes the base plate shared with the zeroth-order resonant antenna, and a first radiation element located on the same plane as the base plate. The first-order resonant antenna is configured to transmit and/or receive a second linearly polarized radio wave perpendicular to the first linearly polarized radio wave by first order resonance.

Abstract: An antenna device includes a ground plate, a patch portion disposed parallel to the ground plate with a particular spacing, a plurality of short circuit portions that electrically connect the patch portion to the ground plate, and a loop portion which is a loop shaped conductor member at a particular spacing from an outer edge portion of the patch portion. The patch portion has an area which forms an electrostatic capacitance that causes parallel resonance with an inductance provided by the short circuit portions at a particular target frequency. The loop portion is formed with a perimeter length which is an integral multiple of the wavelength of radio waves at the target frequency. A feed point is disposed on the loop portion, and current is supplied to the patch portion through the loop portion.

Abstract: A light-transmissive antenna includes: a transparent base made of a transparent insulating material; and an antenna pattern formed on the transparent base. The antenna pattern is made of a transparent electrically conductive film that is a film-like member having a predetermined transmittance and a predetermined electrical conductivity. The light-transmissive antenna includes a plurality of highly electrically conductive patterns arranged on the antenna pattern, each of the highly electrically conductive patterns being made of an electrically conducive member having a higher electrical conductivity than the transparent electrically conductive film and formed in a linear shape. Each of the plurality of highly electrically conductive patterns has a predetermined width set equal to or smaller than a value assumed as a resolution of human eyes.
