Problems solved by technology

However, at present, the occupancy rate of 4G communication in the market is still very large, so the coexistence of 4G network and 5G network has become the current development trend of the industry, but the use of 4G or 5G antenna alone will cost more and occupy more space, and operators will bear higher costs

Embodiment 1

[0037] The multi-frequency array antenna in this embodiment includes a metal reflector 1, four rows of TDD antenna arrays 3 and two rows of FDD antenna low-frequency arrays 4 arranged above the reflector 1, and four rows of TDD antenna arrays 3 are arranged in parallel, and two rows of FDD antenna arrays are arranged in parallel. Antenna low-frequency arrays 4 are arranged symmetrically on the left and right sides of four columns of TDD antenna arrays 3, and each column of FDD antenna low-frequency arrays 4 is composed of several low-frequency radiation units b5, and each low-frequency radiation unit b5 is directly above and on both sides Each is provided with a high-frequency radiation unit a2, and multiple high-frequency radiation units a located on the same side form an FDD antenna high-frequency array 6; the high-frequency radiation unit a2 and the low-frequency radiation unit b5 are coaxially arranged, and two adjacent Only one high-frequency radiation unit a2 is arranged ...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is that the radiating elements c 7 included in any two adjacent columns of the TDD antenna array 3 are staggered, that is, the radiating elements c 7 are misplaced, which can effectively reduce the gap between the arrays. Inter-coupling effect, improve system isolation.

Embodiment 3

[0045] The difference between this embodiment and Embodiment 1 is that only one high-frequency radiation unit a2 is arranged directly above and on the front and rear sides of the low-frequency radiation unit b5 contained in one row of FDD antenna low-frequency array 4, and a plurality of radiation units located on the same side The high-frequency radiation unit a forms the FDD antenna high-frequency array 6; this embodiment is also an array formation method derived from the present invention, which reduces antenna costs while providing 4G and 5G network functions.

[0046] The multi-frequency array antenna of the present invention is composed of an FDD antenna and a TDD antenna. The low frequency band of the FDD antenna is 698MHz~960MHz or 617MHz~894MHz, and the high frequency band is 1427MHz~2690MHz or 1710MHz~2690MHz. The frequency band of the TDD antenna is divided into high and low frequency bands, supporting Dual frequency system, the low frequency range is 2490MHz ~ 2690M...

Abstract

The invention provides a multi-frequency array antenna which can be simultaneously applied to a 4G network and a 5G network, so that the repeated utilization rate of the antenna is greatly increased.The FDD part of a 4G antenna and the TDD part of a 5G antenna are mutually combined and form an array by a multi-frequency array antenna so as to provide the functions of the 4G network and the 5G network; and the FDD part of the 4G antenna is placed on two sides of the TDD part of the 5G antenna to form a compact structure, and the height difference exists between a reflecting plates positioned right below the two rows of FDD antenna low-frequency arrays and a reflecting plate positioned right below the plurality of rows of TDD antenna arrays, so that the influence of radiation generated by the plurality of rows of TDD antenna arrays on the two rows of FDD antenna low-frequency arrays is reduced, and the isolation of a system can be improved. In addition, the high and low frequency arraysof the FDD part in the multi-frequency array antenna are combined in a coaxial nesting mode, so that the length of the antenna is greatly shortened, and the electrical performance index is good.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-frequency array antenna. Background technique [0002] With the rapid development of society, mobile communication has also developed rapidly. In some areas, regional 4G communication can no longer meet people's needs, so 5G communication technology has emerged as the times require. However, at present, the occupancy rate of 4G communication in the market is still very large, so the coexistence of 4G network and 5G network has become the current development trend of the industry, but the use of 4G or 5G antenna alone will cost more and occupy more space, and operators will bear higher costs . Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an FDD+TDD multi-frequency array antenna, which can be used by different system systems at the same time to ensure the coexistence and compatibility of 4G and 5G...
