Abstract

The invention provides a multifunctional integrated active antenna subarray. The multifunctional integrated active antenna subarray comprises a plurality of dry cooling plate assemblies, a comprehensive back plate assembly, a radiator and a fixing plate, and the dry cooling plate assemblies are sequentially arranged on the lower side face of the comprehensive back plate assembly. The fixing plateand the radiator are arranged on the two opposite side faces of the comprehensive back plate assembly. And the fixed plate and the radiator are respectively connected with the dry cooling plate assemblies. According to the invention, the T / R assembly, the feed network, the power supply and the radiator can be integrated, so that the installation is convenient, and the layout can be carried out according to certain rules such as rectangles, triangles and the like according to actual requirements.

Description

technical field [0001] The invention relates to the technical field of phased array radar, in particular to a multifunctional integrated active antenna subarray. Background technique [0002] Radar technology is a multi-disciplinary technology that integrates mechanics, electronics, and heat. With the rapid development of radar technology, users have increasingly high requirements for the miniaturization, modularization, and multi-functionality of radar equipment. The active antenna is easy to realize the miniaturization of the antenna, and can solve the current situation of low efficiency of the passive antenna, and is favored by the antenna designer. The active antenna has a simple and compact structure, and can also reduce the area of ​​the antenna. [0003] Usually, an active array antenna is composed of multiple distributed transceiver units and radiation modules. The frequency, amplitude, and phase of each radiation module can be controlled, and can form single or mult...
