Abstract

The invention discloses a high gain and high efficiency planar antenna. The high gain and high efficiency planar antenna comprises a feed layer, a coupling layer, a resonant cavity layer and a radiation layer, wherein the feed layer, the coupling layer, the resonant cavity layer and the radiation layer are sequentially arranged according to the electromagnetic wave propagation direction. The radiation layer comprises a plurality of radiation units and special-shaped radiators, wherein the special-shaped radiators are in a novel structure. Electromagnetic waves are radiated towards space by the special-shaped radiators, each special-shaped radiator is formed by a double-curved-surface cut conical barrel, and therefore the electromagnetic waves can be radiated out along the double-curved-surface structure portions of the special-shaped radiators in a uniform amplitude and inphase mode, and the double-curved-surface structure portions of the special-shaped radiators can weaken mutual electromagnetic interference of adjacent special-shaped radiators. The high gain and high efficiency planar antenna breaks thinking patterns of an existing planar antenna design structure, the planet planar antenna unique in structure is designed through a great deal of experimental simulation, and therefore the whole planar antenna is compact in structure, low in section and high in gain, and meets existing planet planar antenna technical demands, namely high efficiency, large band width and small size, and efficiency of the planar antenna can be improved by more than 85%.

Description

technical field [0001] The invention relates to a high-gain and high-efficiency panel antenna, which belongs to the technical field of satellite communication panel antennas. Background technique [0002] Panel antennas have the advantages of light weight, small size, less space, small wind resistance, and high efficiency. Compared with other forms of antennas such as parabolic antennas, panel antennas have higher efficiency, higher gain, and smaller size. However, the current panel antenna The efficiency is between 75% and 80%, and it is difficult to break through the efficiency of 80% from the technical level to achieve higher efficiency. [0003] The existing planar antennas have various structures, but most of them only meet the technical conditions of short-distance communication: [0004] For example, Chinese patent application CN101752655A discloses a flat panel antenna, which includes a substrate, multiple antenna bodies and a metal layer. The multiple antenna bodi...
