Abstract

The invention provides a multi-frequency-band electromagnetic integrated mast, wherein, a satellite guiding antenna is in fixed connection with a top end of a centrally penetrating rod, and the centrally penetrating rod sequentially penetrates and is in fixed connection with a UHF1 communication system, a UHF2 communication system, an HF / VHF communication system, and an RF system; a distance between a bottom of the UHF1 communication system and a bottom of the satellite guiding antenna is 0.8~0.9 m, and a diameter of the centrally penetrating rod is 2 cm; a distance between a bottom of the UHF2 communication system and the bottom of the UHF1 communication system is 0.8~0.9 m, and a diameter of the centrally penetrating rod is 2.5 cm; a distance between a top of the RF system and the bottom of the UHF2 communication system is 2.8~3 m, and a diameter of the centrally penetrating rod is 3~4 cm; and a distance between the top of the RF system and the ground is 0.6~0.8 m. The multi-frequency-band electromagnetic integrated mast can cover multiple radio frequency-bands, thus improving an electromagnetic environment and enhancing systematic reliability, and can be small in occupation space and have modular design, thus facilitating multifunctional integration.

Description

Technical field [0001] The invention relates to the fields of electronic technology such as communication and navigation, and in particular to a technical framework of a multi-frequency electromagnetic integrated mast system. Background technique [0002] Many GPS, UHF, HF and other antennas and radio frequency networks have been installed in many communication and navigation stations, vehicles, ships, and even the roofs of buildings in my country. Such a large number of antennas has caused a complex electromagnetic environment and a lot of waste of resources, especially on mobile platforms. One contradiction is more prominent. In order to improve work efficiency and improve the electromagnetic environment, many users expect to effectively integrate the transceiver antennas of various systems, that is, adopt the ideas of integrated antenna, integrated radio frequency, and integrated signal processing, and integrate the platform sensor into an integrated design. Physically cascade...
