Problems solved by technology

Due to the limitation of the beam width of the antenna itself, it is impossible to take into account the beam coverage in the low elevation direction and the zenith direction at the same time
Traditional antennas can no longer meet the communication needs of the ground station system

Abstract

The invention relates to a high-power ground station antenna covered by hemispherical beams. The antenna comprises a radome. The radome comprises a radome body and a bottom plate. A cavity power divider is arranged on the top surface of the bottom plate. The cavity power divider is provided with a printed board fixing plate, a power divider output port and a power divider input port connector. Theomnidirectional antenna printed board assembly comprises an omnidirectional antenna printed board, a printed dipole unit, a printed board input port, a shaping feed network and a high-power chip resistor. The lightning rod assembly is composed of a lightning rod fixing rod and a lightning rod. The high-power cable assembly comprises a first high-power cable, a second high-power cable and a high-power cable connector. The upper end of the first high-power cable is connected with the printed board input port, and the lower end is connected with the power divider output port. The upper end of the second high-power cable is connected with the blind compensation antenna assembly, and the lower end is connected with the power divider output port. The antenna is large in power capacity and widein directional diagram coverage range, has a lightning protection function and is suitable for a ground station communication system.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a high-power ground station antenna covered by a hemispherical beam. Background technique [0002] As an important device for transmitting and receiving radio signals in a radio system, the antenna performance directly affects the communication quality of the entire radio system. With the development of communication technology, the demand for communication capacity is getting higher and higher, the requirement for corresponding antenna gain is getting higher and higher, and the demand for power capacity is getting bigger and bigger. [0003] In long-distance communication systems such as ground stations, the antenna is usually installed at a higher position, which is vulnerable to lightning strikes, and the antenna needs to be protected against lightning. Since the communication target may appear in any direction, in order to achieve high-quality communication, it ...
