MULTI-FREQUENCY ARRAY ANTENNA, RADIATION STRUCTURE AND METHOD FOR ASSEMBLING RADIATION STRUCTURE

The present invention relates to a multi-frequency array antenna, a radiation structure and a method for assembling the radiation structure. The radiation structure comprises a reflection plate and a high-frequency radiation unit. The reflection plate is provided with a first mounting surface; and the high-frequency radiation unit comprises a high-frequency vibrator and a first phase-shift network module, the high-frequency vibrator being electrically connected to the first phase-shift network module to form a mounting module, and the mounting module being fixedly arranged on the first mounting surface. The high-frequency vibrator and the first phase-shift network module are assembled and connected in advance to form the mounting module, and when the whole machine is subsequently assembled, the whole mounting module only needs to be mounted at a preset position on the first mounting surface of the reflection plate, such that the assembly process of the whole machine is simplified, the assembly difficulty is reduced, and the assembly efficiency is improved.
