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...
