Description

Technical Field

[0001] This utility model relates to the field of microwave communication equipment, and in particular to a microwave communication device with an adjustable dual-frequency antenna bracket. Background Technology

[0002] The main subject of this case, an adjustable dual-frequency antenna bracket for microwave communication equipment, can be summarized in two aspects: portability and signal transmission limitations. Existing equipment has high limitations in signal transmission in mountainous areas, disaster areas, or major events. Sometimes it is transported by vehicle, but the rugged mountain roads make it difficult for vehicles and equipment to arrive quickly, causing further impact. Even if it is deployed, the signal transmission is still highly limited. This case, through satellite and mobile communication equipment, can achieve both portability and dual-purpose signal transmission in urban or mountainous areas.

[0003] In existing technologies, microwave communication equipment mainly consists of antennas, transceivers, modems, and multiplexing equipment. The antenna is responsible for converting microwave signals into electromagnetic waves, enabling signal transmission and reception. Microwave communication primarily uses line-of-sight communication. To achieve long-distance communication, relay stations are needed for relay transmission. Like a relay race, the relay station receives digital signals, processes them through frequency conversion and intermediate frequency amplification, and then forwards them to the next station, ensuring signal quality.

[0004] Existing microwave communication equipment has significant shortcomings in portability. Due to the high requirements for size and power of core components such as antennas and transceivers, integration is difficult, making it hard to significantly reduce the size and weight of the equipment. Its convenience in mobile scenarios is mainly limited by the communication distance, which is constrained by the line-of-sight propagation characteristics of microwaves and requires the use of relay stations.

[0005] To address this issue, a microwave communication device with an adjustable dual-frequency antenna bracket is proposed. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides a microwave communication device with an adjustable dual-frequency antenna bracket, aiming to improve the signal limitations and portability issues in the prior art.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the signal is received by the satellite signal receiving device signal receiving board and focused onto the LNB. The LNB then transmits the signal to the signal converter. The signal converter sends the processed microwave signal to the frequency band conversion amplifier, which then converts it into an amplified electrical signal. Finally, the signal is transmitted to the gain antenna through feeder two. This achieves dual-sided signal transmission through two independent signal transmission paths: satellite signal receiving and processing and radio frequency remote unit relay conversion.

After the height of each storage leg is adjusted uniformly, the grounding area can be increased on flat ground, making the device more stable and having better wind resistance. The sliding plate can slide up and down through the carrier. The sliding plate drives the adjustment rod to rotate, and the adjustment rod drives the support leg to reciprocate, thereby realizing the closing and opening of the whole adjustment component, achieving the effect of easy movement and loading and unloading.

The signal receiving board 4 receives satellite signals and focuses them onto the LNB 6. After processing, the LNB 6 transmits the signal to the signal converter 8 via feed 7. The signal converter 8 then transmits the processed microwave signal to the frequency band conversion amplifier 10 via feed 11. The microwave signal is processed by the frequency band conversion amplifier 10 into an amplified electrical signal, which is then transmitted to the gain antenna 2 via feed 12 to achieve signal transmission. The radio frequency remote unit 9 converts and processes the optical signal transmitted from the relay station to form an electrical signal of the same frequency band. The electrical signal processed by the radio frequency remote unit 9 is transmitted to the gain antenna 2 via the threaded feed 13 to achieve signal transmission. This achieves dual-mode signal transmission through two independent signal transmission paths: satellite signal reception and processing, and relay conversion by the radio frequency remote unit 9.

The sliding plate 22 is rotatably connected to one end of the adjustment rod 21. The other end of the adjustment rod 21 is rotatably connected to the corner block 20. The entire adjustment component can be closed and opened by moving the sliding plate 22 up and down. The overall height is controlled by extending and retracting the storage leg 24. The height of each storage leg 24 can be adjusted individually. This solves the problem of adjusting the level height on uneven ground when supporting equipment in mountainous areas, ensuring the stability of the support.
