Abstract

The invention relates to a high-gain efficient panel antenna using a dielectric lens and special-shaped radiators. The antenna comprises a feed layer, a coupling layer, a resonance cavity layer and a radiation layer which are sequentially arranged according to the transmission direction of electromagnetic waves. The radiation layer comprises a plurality of radiation units, each radiation unit comprises one special-shaped radiator and a radiation slot opposite to the special-shaped radiator, and the radiation layer is provided with the dielectric lens. A thinking pattern of a design structure of an existing antenna is broken, and the satellite panel antenna in a unique structure is designed in a simulation mode through a plurality of experiments. Therefore, the panel antenna is compact in structure, low in profile and high in gain, and meets technical requirements of high efficiency, large band width and small size of the existing satellite panel antenna. The efficiency of the panel antenna reaches as high as over 85%.

Description

technical field [0001] The invention relates to a high-gain and high-efficiency panel antenna adopting a dielectric lens and a special-shaped radiator, and 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 CN 101752655A discloses a flat panel antenna, which includes a substrate, multiple ante...
