Description
Technical field
The utility model is related to technology wireless communication technology field, more particularly to a kind of antenna transmission system and base station day
Line.
Background technology
Antenna for base station for mobile communications network, play the role of it is very important, if antenna selection (type,
Position) bad or antenna parameter setting is improper, can all directly affect the running quality of whole mobile communications network.Especially exist
Base station number is more, and stop spacing is little, the high traffic area more than carrier frequency quantity, along with due to wireless caused by surrounding environment influence
Electric wave multipath reflection and block so that area covered, Pilot Interference and multipath effect are increasingly serious in communication network, while also making
Obtain coverage rate percent of call completed and the whole network service quality all has a great impact.Thus it requires the large and small area of Downtilt cover it is close with
And disturb little each other, typically only electrical tilt antenna could preferably meet these requirements.Electrical tilt antenna can be by changing
Collinearly the phase place in array antenna a period of time, the amplitude size of change vertical component and horizontal component and change synthesis component field intensity are strong
Degree, so that the vertical directivity pattern of antenna has a down dip, while and making whole directional pattern that covering is reduced in serving cell sectors
Area but do not produce interference.What therefore electrical tilt antenna can be appropriate solves the above problems.
