Abstract

The present invention relates to the technical field of satellite antennas, especially to a multi-star and multi-frequency passive antenna based on microstrip antenna stack. The antenna comprises an upper housing and a lower housing. The lower end of the lower housing is connected with a fixed block, the lower end of the fixed block is provided with a circular groove, the inner cavity of the circular groove is movably connected with a circular ball, the lower end of the circular ball is connected with a support rod, the two sides of the support rod are connected with fixed plates, the outer sides of the fixed plates are provided with thread long grooves, the two sides of the lower ends of the fixed blocks are connected with flexible tubes through connection blocks, springs are commonly connected between the two flexible tubes and the connection blocks, the springs are located at the outer sides of the flexible tubes, the lower ends of the flexible tubes are connected with pointer rodsthrough support blocks, and the outer sides of the pointer rods are in screw joint with the thread long grooves through bolts. The multi-star and multi-frequency passive antenna based on microstrip antenna stack is reasonable in structure design, convenient to reduce electromagnetic interference intensity, facilitates angle regulation for the antenna, and is rapid and convenient to regulate and low in cost.

Description

technical field

[0001] The invention relates to the technical field of satellite antennas, in particular to a multi-satellite and multi-frequency passive antenna based on stacked microstrip antennas. Background technique

[0002] Satellite navigation has the characteristics of full-time, all-weather, high-precision, continuous and real-time navigation, positioning and timing. In recent years, global positioning system and wireless local area It is getting better and better, so the application of multi-satellite and multi-band antennas in modern wireless communication has attracted much attention.

[0003] However, the work design of the current multi-satellite multi-frequency antenna is cumbersome, and multiple antennas are designed according to multiple frequency bands. Most of them are fixed installation, it is not convenient to adjust the angle, and it is inconvenient to use. Therefore, we provide a multi-satellite multi-frequency passive antenna based on a stacked micro...
