Description
[technical field]
The utility model relates to antenna of mobile communication base station field, particularly, relates to a kind of antenna and antenna isolation assembly thereof.
[background technology]
Antenna for base station is the key position of mobile communication system outdoor cover, and all communication systems all be unable to do without this important antenna-feedback system of antenna.Along with the growth of city telephone traffic, the appearance of the problems such as the raising that people require network quality and the mutual interference of base station network phase, the antenna that directional diagram is adjustable is just more and more subject to paying close attention to widely and applying.
The antenna that directional diagram is adjustable has two kinds, electrical tilt antenna and mechanical antenna.The principle of electrical tilt antenna is by changing the phase place of each oscillator in antenna array, changes the amplitude size of vertical and horizontal component, changes synthetic component field intensity intensity, thereby the height pattern of antenna is had a down dip.Because the field intensity intensity of antenna all directions increases or reduces simultaneously, therefore change the directional diagram kept stable of inclination angle aft antenna, change little.And mechanical antenna is in the situation that tilt angled down is less, can there is not too large variation in directional diagram, once tilt angled down surpasses a threshold value, directional diagram can sharply worsen, and has a strong impact on communication quality.Therefore, electrical tilt antenna is compared mechanical antenna certain superiority.
But use electrical tilt antenna also can be with the problem of serving, along with the change of antenna oscillator field intensity intensity and phase place, the electric current on coupling path changes, and coupling also changes thereupon.Coupling between antenna causes electromagnetic interference, and isolation characterizes the degree of strength of this coupling.The method that the most simply regulates isolation is the spacing that increases oscillator, but so will increase the size of antenna, and affects directional diagram.Therefore, on coupling path, placing obstacles block electromagnetic coupling is the most frequently used method.Yet along with the increase of tilted angle of antenna, the change of directional diagram, the spacer assembly effect of common fixed position is variation thereupon, can not well play buffer action.Isolation reduces, and two polarization of antenna interact, and the noise that can produce, has a strong impact on communication quality.
Therefore, need a kind of antenna and antenna isolation assembly thereof that can change along with the change of Downtilt position badly.
