Broadband dual-polarization directional antenna

Abstract

The invention relates to the technical field of antennas, in particular to a broadband dual-polarization directional antenna which comprises a reflecting plate, an angle adjusting plate, a +45-degreepolarization port and a -45-degree polarization port. The reflecting plate is provided with an angle adjusting plate, a first low-frequency band radiation oscillator, a first medium-frequency band radiation oscillator, a second low-frequency band radiation oscillator, a second medium-frequency band radiation oscillator, a first low-frequency band one-to-four circuit board, a second low-frequency band one-to-four circuit board, a first medium-frequency band one-to-four circuit board, a second medium-frequency band one-to-four circuit board, a first fractional frequency integrated circuit boardand a second fractional frequency integrated circuit board. The +45-degree polarization port and the -45-degree polarization port feed network are connected with the corresponding connecting ends. Theantenna is wide in frequency band, can meet the dual-frequency-band coverage requirements of a 5G network for a low frequency band of 3300 MHz to 3600 MHz and a medium frequency band of 4800 MHz to 5000 MHz, can also meet the frequency band coverage requirements of a WLAN frequency band of 5150 MHz to 5850 MHz, and has the advantages of being good in performance index, small in size, low in cost,simple in structure and installation and the like.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a broadband dual-polarization directional antenna. Background technique [0002] 5G is also called the fifth generation of mobile communication technology, and it is also an extension after 4G. 5G is the main direction of the development of the new generation of mobile communication technology and an important part of the new generation of information infrastructure in the future. Compared with 4G, it will not only further improve the user experience. The Ministry of Industry and Information Technology has announced the 5G frequency band, and plans to use the 3300MHz-3600MHz and 4800MHz-5000MHz frequency bands as the low-frequency and intermediate-frequency working frequency bands of the 5G system. [0003] Existing antenna products are designed for different working frequency bands. Generally, they are relatively large in size and volume. Whether they are compatible or not depe...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a broadband dual-polarization directional antenna, which has the advantages of small size, low cost, simple structure and installation, and good performance indicators, and solves the problem of existing antennas. The product structure is complex, the design is cumbersome, the versatility is poor, and the processing cost is high, which cannot meet the requirements of the 5G system's low-frequency and intermediate-frequency working frequency bands, and can also meet the system application problems of the WLAN frequency band
