Mobile communication is the energetic a kind of modern communications business that begins to grow up in the eighties in 20th century.In the period of short 20, the experience in technical two generations of passing by, the i.e. second generation narrow-band digital technology of the first generation analogue technique of the eighties and the nineties.In the last few years, along with the breakthrough of the broadband technology of radio communication, mobile communication to based on CDMA, had been the development of the third generation technology of feature with broadband communication.
Along with the continuous development of global mobile communication business, number of users sharply increases simultaneously, and type of service is more and more diversified, and frequency resource becomes the bottleneck of mobile communication development.So press for the reusability that adopts some new technologies to improve frequency spectrum.Smart antenna is exactly to realize one of technology of this target.
Smart antenna has improved the performance and the covering of cdma system greatly, can reduce interference to a great extent, thereby improves power system capacity, becomes one of key technology of 3G (Third Generation) Moblie.In actual the use, must resolve the variety of issue that smart antenna brings, and the complexity of the simplified system of trying one's best.
The networking of general T D UWB (Ultra Wideband) Antenna is used, and super wideband integral antenna is also being built a station on probation on a small scale, but its mixer scheme complexity, the two-antenna scheme size is big, and it is low to gain.
The utility model content
The technical problems to be solved in the utility model provides and a kind ofly reduces antenna for base station quantity under the constant situation of every performance index, reduces the compound antenna for base station of TD-SCDMA that takes up room.For this reason by the following technical solutions:
The compound antenna for base station of a kind of TD-SCDMA, comprise two stand-alone antennas, every stand-alone antenna is made of dual polarization oscillator, check-out console and connector, be vertically staggered the formation matrix structure mutually between the dual polarization oscillator of described two stand-alone antennas, be provided with division board between the adjacent dual polarization oscillator, the dual polarization oscillator of every stand-alone antenna is electrically connected the formation feeding network each other, and the check-out console by separately is connected with separately connector.
As a kind of preferred version, the dual polarization oscillator of described two stand-alone antennas is installed on the T type mounting panel, has 4 row, and every row are equipped with 20 dual polarization oscillators.
As another kind of preferred version, the connector of described two stand-alone antennas is respectively BMA type connector and N Connector.
