Problems solved by technology

[0003] 1. Traditional reflector antennas have played a major role in the past few decades, whether it is radar or communication, navigation, remote sensing and telemetry. This type of antenna is also installed on some aircraft. This is because of this The antenna has the characteristics of high gain and low manufacturing cost, but it has great disadvantages in terms of bulkiness, inconvenient disassembly and assembly, and slow tracking speed, which gradually cannot meet the needs of high mobility platforms.
[0004] 2. Traditional array antennas, with the development of technology, have developed rapidly in the past few years, especially

Embodiment Construction

[0027] Below, combine Figure 1-Figure 6 The present invention will be further described.

[0028] In a low-profile highly integrated satellite mobile communication phased array antenna 1, such as figure 1 As shown, it is a layered structure. The phased array antenna is composed of a low-profile microstrip patch antenna, an antenna array skeleton layer 2, a cavity active radio frequency layer 3, a transceiver power distribution network layer 4, a control and power layer 5, and a supporting chassis layer 6. In this system, the sub-systems mentioned above adopt a layered stack structure, arranged from top to bottom according to a certain order relationship, and connected through electrical connectors, control slots, and power supply slots in the middle. The last supporting chassis 6 plays a supporting role for the whole system, such as figure 2 shown.

Abstract

The invention discloses a low-profile highly-integrated satellite mobile communication phased-array antenna which comprises an antenna framework, an antenna unit, a radio-frequency circuit, a wave control, a power device and the like. By the aid of a full-plane structural form, the height of the antenna is reduced, the integrated level of the antenna is improved, the antenna unit is provided with an ultralow-profile micro-strip, the radio-frequency circuit, a feed network, the wave control and a power lamp are provided with tile-type structures, space size is effectively used, space wave beams are scanned by the aid of phased-array technology, and the antenna is high in efficiency.

Description

technical field [0001] The invention relates to technical fields such as low-profile satellite communication, concealed radar, remote sensing and telemetry, and navigation, and specifically relates to a low-profile highly integrated satellite mobile communication phased array antenna. The invention is also particularly suitable for providing technical support for a new type of satellite communication terminal antenna system for vehicle-mounted, airborne and other low-profile satellite mobile communications. Background technique [0002] With the development of antenna technology, it has become a trend to install low-profile phased array antennas on platforms with high mobility, such as high-speed trains, aircraft, and missiles, and it is also the focus of research by many domestic and foreign scientific research institutions and scholars. one of the subjects. In the previous antenna system, there are many antenna forms to choose from, but these forms have various disadvanta...
