Title:
ANTENNA, RADAR SENSING SYSTEM, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/186179
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of antennas, and disclosed thereby are an antenna, a radar sensing system, and an electronic device. The antenna comprises: a first antenna structure (101), extending in a first direction and having a first side (111) and a second side (121); a plurality of second antenna structures (102) that are arranged in the first direction, are connected to the first side (111), and extend by k1 * (λ / 2) in a direction away from the first side (111); and a plurality of third antenna structures (103) that are arranged in the first direction, are connected to the second side (121), and extend by k2 * (λ / 2) in a direction away from the second side (121). The second antenna structures (102) and the third antenna structures (103) are arranged at intervals in the first direction. One of k1 and k2 is a positive integer greater than 1, and the other one of k1 and k2 is a positive integer greater than or equal to 1. The present invention at least facilitates increasing the radiation angle range of the antenna without significantly increasing the complexity and power loss of the antenna.
