Title:
ANTENNA DEVICE AND BEAM DIRECTION ADJUSTMENT METHOD FOR SAME
Document Type and Number:
WIPO Patent Application WO/2018/006260
Kind Code:
A1
Abstract:
An antenna device and a beam direction adjustment method for same. The antenna, comprising: an antenna element, a metal element, and a substrate. The antenna element and the metal element are separately provided on the substrate, and the metal element is distant from the antenna element by a preset distance on the substrate; the antenna element at least works at a first frequency, and a grounding point of the metal element is fixed to a bonding pad on the substrate, and is located on the side of the metal element proximate to the antenna element; a first reverse current, having a direction opposite to that of an antenna current generated by the antenna element, is coupled out of the side position of the metal element proximate to the antenna element, and a second reverse current, having a direction opposite to a substrate current generated by the substrate, is coupled out of the lower position of the metal element contacting the substrate, so that an upper hemisphere directivity diagram of the antenna element passes through the combination of the first reverse current and the antenna current as well as the combination of the second reverse current and the substrate current, thereby increasing the beam width.
