Multi-beam antenna

Abstract

Embodiments of this application disclose a multibeam antenna. The multibeam antenna can implement beam coverage in at least two directions by feeding through at only one end. There is no need to dispose a complex feeding network, thereby facilitating miniaturization of the multibeam antenna. The multibeam antenna in the embodiments of this application includes: a substrate, an antenna element, a first guiding apparatus, and a second guiding apparatus. The antenna element, the first guiding apparatus, and the second guiding apparatus are disposed on the substrate. The antenna element includes a first pole and a second pole. The first pole is configured to receive a feeding signal. The second pole is grounded. The first guiding apparatus is configured to enable a first beam generated by the antenna element to radiate in a first direction. The second guiding apparatus is configured to enable a second beam generated by the antenna element to radiate in a second direction. A phase center of the antenna element is located at an intersecting point of a first axis and a second axis. The first axis passes through a phase center of the first guiding apparatus and is parallel to the first direction. The second axis passes through a phase center of the second guiding apparatus and is parallel to the second direction.
