Description

Technical Field

[0001] The present application relates to the field of antennas, and in particular to a high- and low-frequency array antenna. Background Art

[0002] In recent years, with the increase in mobile communication network standards, in order to save site and antenna resources, reduce the difficulty of property coordination, and reduce investment costs, co-located multi-frequency array antennas have become the first choice for network construction. In existing wireless communication systems, MIMO (Multiple-Input Multiple-Output) antenna technology is an important key technology for improving the quality and efficiency of mobile communications. The use of MIMO technology can greatly increase channel capacity, improve channel reliability, and reduce bit error rate; however, with the increasing number of array antenna frequency bands and arrays, the interference between arrays is becoming more and more serious. In order to reduce this interference while ensuring that the antenna size is relatively small, better realize the transmit and receive diversity effect of MIMO multi-antennas, and improve the application scenarios of array antennas, the research on antenna array configuration schemes is of great significance;

[0003] For example, patent number (CN201710058947.1) discloses a multi-frequency antenna array with a high-low frequency combination, comprising a low-frequency array composed of low-frequency oscillators and a first high-frequency array, a second high-frequency array, and a third high-frequency array composed of high-frequency oscillators. The invention is characterized in that: in the middle of the antenna is a dual-frequency array composed of a low-frequency array and a first high-frequency array coaxially nested, the second high-frequency array and the third high-frequency array are distributed on both sides of the dual-frequency array in a shoulder-to-shoulder staggered manner, and the spacing between the high-frequency oscillators in the second high-frequency array is equal to the spacing between the high-frequency oscillators in the third high-frequency array; the coaxial nesting of the low-frequency array and the first high-frequency array is implemented in that a low-frequency oscillator is provided around every other high-frequency oscillator in the first high-frequency array; the shoulder-to-shoulder staggered distribution includes that, along the longitudinal direction of the antenna, the distances from any high-frequency oscillator in the first high-frequency array in the dual-frequency array to the two nearest high-frequency oscillators in the second high-frequency array or the third high-frequency array are unequal;

[0004] However, in the above structure, multiple antenna arrays are involved. Such densely placed antennas will generate a lot of dust in daily reality. The existing cleaning method is to clean the dust on the antenna by blowing air; but it is all cleaned manually. Due to the large number of antennas and their relative density, cleaning is troublesome and not uniform enough.

[0005] Currently, there is no high and low frequency array antenna that is easy to clean dust from the antenna and has a uniform cleaning effect. Summary of the Invention
