Mesh-network-based integral complete coverage phased-array antenna

Abstract

The invention belongs to the field of microwave communication, and particularly relates to a mesh-network-based integral complete coverage phased-array antenna. The antenna comprises an intelligent control unit, a radio frequency unit, a filter, a combiner and an antenna array, wherein the antenna array comprises four sectors which are arranged in a square shape; the intelligent control unit, the radio frequency unit, the filter and the combiner are arranged in a tetrahedron formed by the antenna array; each sector of the antenna array is correspondingly provided with a T / R component and a phase shifter unit; the antenna array is connected with each T / R component by a plate connector; each T / R component is connected with the corresponding phase shifter unit by a radio frequency connector; each phase shifter unit is connected with the combiner by a radio frequency cable. The mesh-network-based integral complete coverage phased-array antenna has the characteristics of narrow wave beam, low sidelobe and high gain, improves the system coverage area, increases the communication distance and communication allowance between network nodes, and improves the reliability of system communication.

Description

technical field [0001] The invention belongs to the field of microwave communication, and in particular relates to an integrated full-coverage phased array antenna based on a mesh network. Background technique [0002] The existing phased array technology is usually based on sector scanning of an array, which is usually used in radar systems to monitor and track various aircraft and other targets such as artificial satellites, intercontinental ballistic missiles, and space shuttles. Its 360-degree Coverage antennas are usually discrete and not used in mesh network architectures. Mesh network communication usually uses omnidirectional antennas for communication between nodes. The disadvantages of using omnidirectional antennas are poor directivity and low gain, resulting in small system coverage, short communication distances, and less communication margin. Therefore, the problem of full coverage cannot be better solved. Contents of the invention [0003] In order to sol...
