Horizontal scanning conformal array antenna

Abstract

The invention discloses a horizontal scanning conformal array antenna. The horizontal scanning conformal array antenna comprises a mounting chassis and multiple antenna units which are uniformly distributed on concentric circles taking a center of the chassis as a circle center, wherein each antenna unit is connected with a coaxial feeding cable, a lower surface of an antenna shield is mounted on the mounting chassis, a phase control electric scanning device is connected with the antenna units through the coaxial feeding cables, and wave beam scanning in all directions can be realized through controlling phase of each antenna unit. The conformal array antenna is advantaged in that the structure is simple, the antenna can be conformal with an unmanned plane or a missile platform and can be hidden in a carrier sheath, good pneumatic characteristics and good electric index of a carrier are maintained, a radiation field of the antenna can realize uniform high gain scanning in a horizontal 360-DEG scope, and cooperation networking demands of the unmanned plane or a missile communication system can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of array antennas, and relates to a conformal array antenna for horizontal plane scanning, in particular to an array antenna capable of realizing horizontal plane scanning and conformal to the surface structure of high-speed moving carriers such as drones and missiles. Background technique [0002] At present, the fields of civil aircraft (especially unmanned aerial vehicles) and military missiles have proposed collaborative networking requirements. Cooperative networking of UAVs means that the communication between multiple UAVs does not completely depend on basic communication facilities such as ground control stations or satellites, but uses UAVs as network nodes, and each node can forward command commands to each other and exchange perceptions. Situation, health status and other data, automatically connect to establish a wireless mobile network, and the collaborative application of multiple UAV systems h...
