Abstract
An antenna device includes an antenna unit and reflecting units. The antenna unit is arranged on a substrate. The reflecting units are arranged separately from each other on the substrate and surrounding the antenna unit. The reflecting units are configured to adjust a radiation pattern of the antenna unit, and each of the reflecting units includes a first portion and a second portion. The first portion has an upper side and a lower side, and the lower side of the first portion is coupled to the substrate. The second portion has a lower side connected to the upper side of the first portion. A width of the lower side of the first portion is smaller than a width of the lower side of the second portion.
Claims9
An antenna device, comprising:
- an antenna unit arranged on a substrate;
- and
- a plurality of reflecting units arranged separately from each other on the substrate, surrounding the antenna unit, wherein the reflecting units are configured to adjust a radiation pattern of the antenna unit, and each of the reflecting units comprising:
- a first portion having an upper side and a lower side;
- and
- a second portion having a lower side connected to the upper side of the first portion;
- and
- a first switch coupled to the substrate and the lower side of the first portion;
- wherein the substrate coupled to the lower side of the first portion through the first switch and a width of the lower side of the first portion is smaller than a width of the lower side of the second portion,
- wherein a number of the reflecting units is three, and the antenna unit is arranged on a perpendicular bisector of an edge of an isosceles triangle formed by the reflecting units, and
- wherein a distance between a first reflecting unit of the reflecting units disposed on the perpendicular bisector and the antenna unit is greater than a distance between each of the other two reflecting units of the reflecting units and the antenna unit, and a width of the lower side of the second portion of the first reflecting unit is the largest one of widths of the lower sides of the second portions of the reflecting units.
An antenna system, comprising:
- a control circuit;
- and
- a plurality of antenna devices coupled to the control circuit, wherein the control circuit is configured to control corresponding radiation patterns of the antenna devices, wherein each of the antenna devices comprises:
- a plurality of reflecting units, and each of the reflecting units comprising:
- a connecting portion having a first side and a second side opposite to the first side;
- a radiation pattern adjusting board having a first side and a second side opposite to the first side, and the first side of the radiation pattern adjusting board connected to the second side of the connecting portion;
- and
- a first switch coupled to a substrate and the first side of the connecting portion, wherein the substrate coupled to the first side of the connecting portion through the first switch and a width of the first side of the connecting portion is smaller than a width of the first side of the radiation pattern adjusting board;
- and
- an antenna unit surrounded by the reflecting units,
- wherein a number of the reflecting units is three, and the antenna unit is arranged on a perpendicular bisector of an edge of an isosceles triangle formed by the reflecting units, and
- wherein a distance between a first reflecting unit of the reflecting units disposed on the perpendicular bisector and the antenna unit is greater than a distance between each of the other two reflecting units of the reflecting units and the antenna unit, and a width of the first side of the radiation pattern adjusting board of the first reflecting unit is the largest one of widths of the first sides of radiation pattern adjusting boards of the reflecting units.
