Body is a kind of equivalent strip line phase shifter of multi-port modular and its transmission system.
Background technology
In a wireless communication system, antenna for base station plays extremely communication quality as the important component in mobile communication system
Close important role.In the network coverage, to make signal well cover, generally requires and certain angle is carried out to antenna for base station main beam
The inclination of degree, there are two ways to realizing that main beam has a down dip:Mechanical tilt and electricity tune have a down dip.Electricity is adjusted and is had a down dip relative under machinery
Incline, increasing sector angular can be such that sector coverage product reduces, but not generate interference;In addition electrical tilt antenna adjusts the angular accuracy that has a down dip
Height, maintenance personnel can carry out remote control adjustment to antenna for base station.And phase shifter technology adjusts the core for the technology that has a down dip as electricity,
It can realize this target.
The phase shifter applied in antenna for base station is divided into two major classes:The first kind is physical length variable phase shifter, and the second class is
Medium sliding-type phase shifter.Physical length variable phase shifter changes phase by changing the physical length of signal transduction pathway;
Medium sliding-type phase shifter changes phase by changing the effective dielectric constant of transmission line.
It is asked since physical length variable phase shifter always exists that inevitable intermodulation stability is difficult, and Insertion Loss is higher etc.
Topic, more and more units use medium sliding-type phase shifter instead now.
Existing antenna for base station design producer emphasis point is all:How the performance indicator and welding efficiency of phase shifter are improved
Often consider from cavity body structure or appearance Deng, means, as application publication number CN 104051821A state this phase shifter
Several guide rails are equipped in cavity, to improve electricity function index;104681896 A of application publication number CN state this
Phase shifter section is low, volume-diminished, and pad is few, and mutual tonality is good;10606757 A of application publication number CN state this phase shift
Taking for both sides welding is reduced in 4 pad hole positions of device in side, increases conduction chamber outside cavity, reduces intermodulation effects.More than
These patents are set about from phase shifter configuration aspects itself, propose creative conclusion.And multiport and combined type are moved
The research of phase device is less, does not generate substantive creative conclusion.
