The invention discloses a reconfigurable antenna device from an omnidirectional antenna to a phased array, and relates to the technical field of navigation communication between the ground and an aircraft. The antenna device comprises a tower pipe, a multi-column directional antenna, a power divider, a first connector and a second connector; the multi-column directional antenna is arranged at the periphery of the tower pipe, the power divider is arranged at the lower end of the tower pipe, the first connector and the second connector are arranged on the multi-column directional antenna, and the power divider is connected with the multi-column directional antenna through the first connector and the second connector. The antenna device has the advantages that the device can be installed on the standard iron tower pipe, a corresponding installation tower pipe does not need to be specially manufactured, when an omnidirectional antenna is used, the good out-of-roundness characteristic is achieved, and when a phased array is reconstructed, tracking wave beams and sector wave beams can be generated.
Description
technical field [0001] The invention relates to the technical field of navigation communication between ground and aircraft, in particular to a reconfigurable antenna device from an omnidirectional antenna to a phased array. Background technique [0002] In the field of wireless communications, with the establishment of China Tower Corporation, the co-construction and sharing of telecommunications infrastructure has been further strengthened. Telecom base stations are constructed by China Tower Corporation through centralized resources, unified planning, and overall arrangements. Other units are not qualified to build base station towers according to their own network planning and antenna structure, so they can only rent the already built towers and design their own antennas based on the tower structure. [0003] In the field of mobile communication, usually, the 360° azimuth plane is divided into three sectors with the iron tower as the center, and each sector is covered b...
