Description

Multi-frequency antenna

Technical field

The invention relates to a multi-frequency antenna, which is mainly applied in the field of wireless communication.

Background technique

With the continuous development of the wireless communication industry, the application of multi-frequency antennas is becoming more and more extensive; and the horizontal wave width of frequency is one of the important factors affecting multi-frequency antennas. Generally, the larger the horizontal wave width, the coverage area at the sector boundary. The larger the spread, the larger the range of propagation. However, once the tilt angle of the antenna is increased, beam distortion is easily generated to form a cross-region coverage. The smaller the horizontal wave width, the worse the coverage area at the sector boundary is. When the dip angle of the antenna is used, the coverage at the sector boundary can be improved to the extent of the movement, and relatively, the coverage is not easily generated. Therefore, for multi-frequency antennas, the ideal horizontal wave width is an important factor in measuring its quality.

In this regard, an improved method is adopted in the patent document CN2658958, in which one column of radiators outputs one frequency band and the other column of radiators outputs another frequency band, and the two columns of radiators are arranged in a staggered position in the vertical direction, and are used for one column. A method of adding an additional radiator to another radiator in the radiator to reduce the angle of the horizontal wave width. However, this method not only has a complicated antenna layout, but an increased radiator may also cause the antenna to be unachievable and the isolation is poor. In addition, when the spacing between the two columns of radiators is very close, the horizontal wave width of each column of radiators is divergent, and the low frequency F1 is too wide, for example, when the spacing between the two columns is 0.3-0.7 wavelengths, the low frequency wave width is It may reach 75-110 degrees, which cannot meet the wave width requirement of the communication antenna (usually the typical horizontal wave width requires 65 degrees).
