Multibeam antenna

A multibeam antenna, comprising:

• a substrate;
• an antenna element;
• a first guiding apparatus;
• and
• a second guiding apparatus;
• wherein the antenna element, the first guiding apparatus, and the second guiding apparatus are disposed on the substrate;
• wherein the antenna element comprises a first pole and a second pole, the first pole is configured to receive a feeding signal, and the second pole is grounded, the first pole defines a first end of the antenna element, the second pole defines a second end of the antenna element, a major axis of the first pole is aligned with a major axis of the second pole in a plan view, a first virtual line is aligned with a major axis of the first guiding apparatus, a second virtual line is aligned with a major axis of the second guiding apparatus, the second end of the antenna element is farther than the first end of the antenna element from an intersecting point of the first virtual line and the second virtual line, the intersecting point of the first virtual line and the second virtual line is an intersecting point in a plan view of the multibeam antenna, and a length of the antenna element is less than a length of the first guiding apparatus and a length of the second guiding apparatus;
• wherein the first guiding apparatus is configured to enable a first beam generated by the antenna element to radiate in a first direction, wherein the second guiding apparatus is configured to enable a second beam generated by the antenna element to radiate in a second direction;
• and
• wherein a phase center of the antenna element is located at an intersecting point of a first axis and a second axis, wherein the first axis passes through a phase center of the first guiding apparatus and is parallel to the first direction, and wherein the second axis passes through a phase center of the second guiding apparatus and is parallel to the second direction.
