Ultra-wideband multi-system narrow-beam array antenna

Abstract

The invention relates to the technical field of the communication antenna, in particular to an ultra-wideband multi-system narrow-beam array antenna comprising a reflective floor, low-frequency oscillators, high-frequency oscillators, first metal baffles, a second metal baffle, and a dielectric plate. The low-frequency oscillators and the high-frequency oscillators are fixedly installed on the reflective floor; the first metal baffles are installed between the high-frequency oscillators below a low-frequency array and are fixedly connected to the reflective floor; the second metal baffle is fixedly installed in the middle of the reflective floor; and the dielectric plate is installed above a high-frequency array. According to the invention, the antenna has the mutually independent antennaarray systems; on the basis of the integrated embedded design, the usage rate of the space of the base station is increased substantially, the antenna number of the base station is reduced, and the mounting difficulty is reduced; and with the narrow beam design, the narrow arterial traffic scene is covered effectively, so that the high-speed train penetration coverage rate during the high-speed operation is guaranteed, the operation cost and the resource wasting are reduced, energy conservation and emission reduction effects are realized, and the visual pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of communication antennas, in particular to an ultra-wideband multi-system narrow beam array antenna. Background technique [0002] With the progress of the society and the continuous development of the national economy, the construction of my country's high-speed rail is advancing at an unprecedented speed. The gradually improved high-speed rail transportation network provides people with great travel convenience. With the gradual improvement of national living standards, people's travel needs Frequency and quality requirements are increasing, including demands on mobile networks. Due to the rapid movement of the high-speed rail, the requirements for switching between networks are extremely high, and at the same time, the loss of wireless signals is also large. In addition, the penetration loss of wireless signals by the vehicle body increases the requirements for antenna gain. The network coverage of high-s...

Problems solved by technology

Moreover, my country's communication network is complex, and it is inevitable that multiple communication application standards will continue to exist. The same base station will coexist with 2G, 3G, and 4G networks, and even 5G will be involved in the later stage, and the interference between different network standards will also be serious. , the traditional antennas are independent dual-polarized antennas, and the beam is wide, the horizontal lobe angle is large, there are many disadvantages such as bulky, large space occupation, serious visual pollution, complicated installation, high operating costs, and difficult maintenance.
