Description

technical field [0001] The invention belongs to the technical field of antennas, and in particular relates to a pointed holographic antenna. Background technique [0002] With the development of antenna technology, holographic antenna came into being. Compared with the traditional reflector antenna, the holographic antenna can obtain the required radiation characteristics by changing the holographic structural components according to the application environment and actual needs, without the need for a fixed contour structure, and has better concealment. [0003] Currently, holographic antennas may include waveguide horn components and holographic structural components. The electromagnetic wave radiated by the waveguide horn part can form a radiation pattern through the holographic structure part. [0004] However, due to the different propagation distances of the electromagnetic wave in the waveguide horn part, a phase difference may occur, thereby affecting the generation...
