Via the polarization orthogonality of the plus 45-degree angle and the minus 45-degree angle in the dual-polarized antenna with the structure aforementioned, the isolation degree between a plus 45-degree antenna and the minus 45-degree antenna can be ensured to meet the requirement of interchange on the isolation degree between the antennas, a space interval is small, and a space volume is reduced; and the oscillator is integrally stamped to be T-shaped by the strip-shaped aluminium material, so that the dual-polarized antenna is simple in structure and low in manufacturing cost.
Description
Technical field
The present invention relates to a kind of antenna for base station, particularly a kind of positive and negative 45 ° of Bipolarization antenna for base station.
Background technology
In cell mobile communication systems; Antenna is communicating equipment circuit signal and the electromagnetic transducer of space radiation; Be the bridgehead of spacing wireless communication, so antenna for base station is the important component part of GSM, its characteristic directly influences the overall performance of whole wireless network.In the mobile radio communication engineering design, should come reasonably to select antenna for base station according to the actual conditions such as covering requirement, telephone traffic distribution, anti-interference requirement and network service quality of network.
The directional base station (three sectors) of traditional G SM digital mobile communication network will use 9 antennas at present, 3 antennas of each fan-shaped use (space diversity, one two receipts), and antenna amount is many, and the space interval between the adjacent antenna is big, and weight is big, and installation requirement is high.
Dual polarized antenna is an a kind of new antenna technology, made up+45 ° with the mutually orthogonal antenna of-45 ° of two consequent pole direction and be operated in simultaneously under the transmission duplex pattern, so its most outstanding advantage is to save the antenna amount of single directional base station; And because dual polarized antenna is not high to setting up installation requirement; Need not take over the land for use and build tower; The iron prop that only needs a diameter 20cm of frame is fixed on dual polarized antenna on the iron prop by corresponding coverage direction and gets final product, thereby saves capital expenditure; Make station layout more reasonable simultaneously, the selected of site, base station is more prone to.But still have certain defective: present dual polarized antenna complex structure, single, manufacturing cost is high, can't be satisfied with the use of various varying environments.
Summary of the invention
The technical problem that the present invention will solve provides a kind of positive and negative 45 ° of Bipolarization antenna for base station of simple in structure, low cost of manufacture.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of positive and negative 45 ° of Bipolarization antenna for base station; Its innovative point is: comprise reflecting plate, the reflecting surface of reflecting plate is provided with some radiating elements, and the feeder network that is electrically connected with radiating element is established at the back side of reflecting plate; Radiating element is assumed diamond in shape by four oscillators and rearranges, and oscillator is stamped into T shape by a strip aluminium integral body, and each oscillator major axis and reflecting plate bearing of trend are 45 ° of angles; The oscillator arms of oscillator is connected with the feed line of feeding network through feed tab, and 45 ° of symmetrically arranged feed lines are aimed at 45 ° of polarization ,-45 ° of polarization of-45 ° of symmetrically arranged feed lines alignings.
The invention has the advantages that: the dual polarized antenna of said structure, ± 45 ° polarization orthogonal property can guarantee+and isolation between 45 ° and-45 ° of two slave antennas satisfies the requirement of intermodulation to isolation between antennas, and space interval is little, reduces spatial volume; Oscillator is stamped into T shape, simple in structure, low cost of manufacture by a strip aluminium integral body.
