Problems solved by technology

If you simply install three antennas with different functions on the buoy, there will be more problems, specifically, including: 1. Mutual interference between multiple antennas will cause electromagnetic compatibility problems; 2. Increased The exposed volume of the buoy antenna exposes the target and reduces the safety and flexibility of the buoy operating the antenna

Embodiment Construction

[0012] A three-in-one buoy antenna, which includes

[0013] Waterproof and sealed structure 14, waterproof and sealed structure 14 includes a base 2; Beidou satellite communication antenna 1 and 9GHz antenna 4 are arranged inside the sealed structure 14, and Beidou satellite communication antenna 1 adopts a multi-layer microstrip antenna structure , and through the Lange coupler circuit to achieve orthogonal feeding and transceiver isolation, the 9GHz antenna adopts a shaped microstrip array structure, and the shaped microstrip array structure consists of 6 pairs of 2-unit microstrip patches shaped on a hexagonal prism support The antenna is composed of: VHF antenna, the VHF antenna reuses the base 2 and the hexagonal prism bracket as the radiator, and uses the entire buoy body 7 as the ground of the antenna. One end of the radiator is connected with a VHF matching network 11 for impedance matching.

[0014] The waterproof sealing structure 14 is arranged on the outside of th...

Abstract

The invention relates to a triad buoy antenna, which comprises a waterproof sealing structure body; the waterproof sealing structure body includes a pedestal, a beidou satellite communication antenna, 9 GHz antenna and a VHF antenna; wherein, the beidou satellite communication antenna and the 9 GHz antenna are arranged in the sealing structure body; the beidou satellite communication antenna adopts a multilayer microstrip antenna structure and realizes orthogonal feeding and transmitter and receiver isolation through a Lange coupler circuit; the 9 GHz antenna adopts a shaped microstrip array structure which is formed by the 6 pairs of two units microstrip patch antennas which are shaped in a bracket of a hexagonal prism; the VHF antenna reuses the pedestal and the bracket of a hexagonal prism as a radiator, one end of which is connected with a VHF matching network used for impedance matching. The beidou communication antenna, the 9 GHz antenna and the VHF antenna are used by being matched with the communication equipment arranged inside a buoy, thus realizing telecommunication, middle-range communication and short-range communication respectively.

Description

technical field [0001] The invention relates to a buoy antenna, especially a three-in-one buoy antenna, which integrates a Beidou satellite communication antenna, a 9GHz horizontally polarized omnidirectional antenna, and a VHF vertically polarized horizontal omnidirectional antenna, and is installed on the top of a steel buoy. When working, it is carried by the buoy and floats freely on the sea surface. Background technique [0002] For Beidou satellite communication, 9GHz communication, and VHF communication, an independent antenna with a single function is used. However, the antennas with the above three functions are integrated to form a pair of multifunctional antennas, and no information has been published yet. [0003] The comprehensive use of Beidou satellite antennas, 9GHz communication antennas and VHF communication antennas can effectively cover long, medium and short distances, undoubtedly providing a strong guarantee for communication and security. However, du...
