Embodiment Construction

[0016] The present invention will be further described now in conjunction with accompanying drawing.

[0017] combine image 3 , Figure 4 , a light and small phased array antenna structure comprising: box frame 1, air heat exchanger 2, transfer module 4, control module 5, tile sub-array 7, antenna transfer board 8, antenna sub-array 9, radome 10.

[0018] The bottom of the box frame 1 is processed with the installation interface of the gas heat exchanger 2, and the gas heat exchanger 2 is installed on the bottom of the box frame 1 through the gas heat exchanger gasket 12; sliders are installed on both sides of the bottom of the box frame 1 3. The height of the bottom surface of the slider exceeds the electrical connector at the bottom of the adapter module 4, which protects the electrical connector and serves as a handling handle for easy transportation.

[0019] An adapter module 4 is installed on the back of the box frame 1 . External electrical connectors are distribut...

Abstract

The invention provides a light and small phased-array antenna, which belongs to the field of radar antenna combination devices. A gas heat exchanger is mounted at the bottom of a box body frame of thephased-array antenna; a switching module is mounted on the back of the box body frame; a control module penetrates through the switching module from the back of the box body frame, enters the box body frame and is mounted on the box body frame; a tile sub-array is installed in the box body frame; the front end surface of the tile sub-array is connected with an antenna adapter plate; the antenna adapter plate is connected with the front end surface of the box body frame; an antenna sub-array is installed on the front end surface of the antenna adapter plate; a radome is installed on the outeredge of the front end face of the box body frame. The phased-array antenna is suitable for the size and weight limitation of a light and small phased-array antenna. The heat dissipation problem of a high-power-consumption assembly in a radar antenna is effectively solved, and normal and continuous work of the phased-array antenna is achieved.

Description

technical field [0001] The invention belongs to the field of radar antenna combination devices. Background technique [0002] With the rapid development of electronic technology and the continuous improvement of military equipment requirements, the integration of phased array antennas is getting higher and higher. In the limited space of the antenna, it becomes more and more difficult to arrange the antenna module reasonably and maintain a relatively stable working environment inside the antenna through the environmental control system to ensure the effective operation of the antenna. [0003] Patent CN208690500U proposes a phased array antenna structure, which divides functional modules and circuit structures, precisely designs the mechanical and electrical interfaces between modules, reduces the correlation between components, and maximizes the efficiency of parallel work. However, the above-mentioned patents are only aimed at small-sized, low-power phased array antennas,...
