Antenna device

摘要

An antenna device includes a first substrate, a feeder line which is disposed in the first substrate, a grounding conductor which is disposed in the first substrate, a first radiation element which is electrically connected to the feeder line in the first substrate, a second radiation element which is electrically connected to the grounding conductor and is disposed substantially in parallel with the first radiation element in the first substrate, a first reflector which is disposed in the first substrate, and a second reflector which is disposed in the first substrate so as to be separated by a predetermined distance from the first radiation element or the second radiation element in at least one of longitudinal directions of the first radiation element and the second radiation element.

1. An antenna apparatus comprising:
a first substrate; a feeding line which is disposed in the first substrate; a ground plane which is disposed in the first substrate; a first radiation element which is electrically connected to the feeding line in the first substrate; a second radiation element which is electrically connected to the ground plane and is disposed in parallel with the first radiation element in the first substrate; a first reflector which is disposed in the first substrate; a second reflector which is disposed in the first substrate and is separated by a predetermined distance from the first radiation element or the second radiation element in at least one of longitudinal directions of the first radiation element and the second radiation element; and a director which is disposed in the first substrate and is separated by a predetermined distance from the first radiation element and is disposed on an opposite side to the first reflector with respect to the first radiation element, wherein the second reflector is disposed at a position so that a longitudinal direction of the second reflector and the longitudinal direction of the first radiation element are perpendicular to each other.
