Abstract
The utility model discloses a multi-sector antenna, which comprises a plurality of the same or different single sector antennae through close connection, said single sector antenna includes a unit omnidirectional antenna and a reflecting plate, unit omnidirectional antenna is fixed on reflecting plate by means of positioning clamp, said unit omnidirectional antenna goes out of pedestal to connect with joint, both ends of said reflecting plate are fixed on end cover, pedestal respectively. The utility model adopts omnidirectional antenna plus reflecting plate to form single sector antenna to adjust horizontal plane beam width to the required angle, vertical plane beam is controlled by omnidirectional antenna beam, beam control of horizontal plane and vertical plane is separated, easy for testing, then a plurality of single sector antennae form multi-sector antenna, in this way, antenna could work with single sector separately, and may work with multi-sector simultaneously, has advantages of both directional covering of directional antenna, and omnibearing covering of omnidirectional antenna.
Description
Technical field
The utility model relates to the mobile communication antenna field, relates in particular to a kind of multi-sector antenna that is used for the mobile communication base station.
Background technology
Existing mobile base station antenna generally is divided into directional antenna and omnidirectional antenna.The characteristics of omnidirectional antenna are horizontal plane 360 degree overlay areas, and area coverage is big, and it is few and require the big place of area coverage to be mainly used in telephone traffic; The characteristics of directional antenna are that horizontal plane is not the comprehensive coverings of 360 degree, but be used for directed the covering, and only cover the zone of appointment, be mainly used in the big hot spot region of telephone traffic, be used to absorb more telephone traffic, be used for the covering that cell splitting becomes microcellulor and Pico cell sub-district.Because directional antenna and omnidirectional antenna all have separately, so, just can realize the characteristics of the multifunction of antenna if both characteristics can be combined on the same antenna.But existing plate antenna mostly is the fully closed reflecting plate antenna of a kind of band radome, reflecting plate is in radome inside, antenna inside is by the air microstrip line, strip line or cable are given the oscillator feed, are used for control phase and amplitude, and this makes the processing technology complexity of entire antenna, the cost height, and be difficult for debugging, because the corner reflection unit is a plate antenna, so the corner reflector antenna manufacture craft is equally also very complicated.
The utility model content
Problem to be solved in the utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, easy to manufacture, easy multi-sector antenna of debugging is provided.
The technical scheme that the utility model adopted is: multi-sector antenna mainly by a plurality of same or different single fan antennas by closely connecting and composing, described single fan antenna comprises a root unit omnidirectional antenna and a reflecting plate, the unit omnidirectional antenna is fixed on the reflecting plate by positioning fixture, preferably fix by at least one locator card, described unit omnidirectional antenna passes base and joint joins, and described reflecting plate two ends are separately fixed on end cap, the base.
Be dustproof and waterproof, described multi-sector antenna between end cap, base also outside coated with outer cover.
Also have leaking hole on the described base, to prevent because the gathering of the condensed water that the radome internal-external temperature difference forms, thereby influence the electrical property of antenna.
Described base also closely is connected and fixed a carriage.
Described unit omnidirectional antenna can be the antenna of any gain, can change the front and back ratio of antenna by changing the height of positioning fixture, and electrical properties such as secondary lobe meet the requirements of index.
The beneficial effects of the utility model are: the form that the utility model adopts omnidirectional antenna to add reflecting plate constitutes the angle that single fan antenna is adjusted to the horizontal plane beamwidth needs, the vertical plane wave beam is then controlled by the omnidirectional antenna wave beam, the control of the wave beam of horizontal plane and vertical plane is separated like this, make that debugging is easy, as long as the distance between accommodation reflex plate and the omnidirectional antenna just can obtain the index that single fan antenna requires, form multi-sector antenna by a plurality of (at least three) single fan antenna again, this antenna can single sector work independently (being directional antenna this moment) like this, also can many sectors work simultaneously (being omnidirectional antenna this moment), the directed characteristics that cover of directional antenna are promptly arranged, also kept the characteristic of the comprehensive covering of omnidirectional antenna.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1, the described multi-sector antenna of the utility model embodiment comprises end cap 1, outer cover 2, locator card 3, unit omnidirectional antenna 4, reflecting plate 5, joint 6, base 7 (above have leaking hole), carriage 8, wherein unit omnidirectional antenna 4 is fixed on the reflecting plate 5 by locator card 3, locator card 3 is fixed on the reflecting plate 5, and reflecting plate 5 upper ends are fixed on end cap 1, and the lower end is fixed on the base 7; Outer cover 2 is fixed between end cap 1 and the base 7 and combines closely; Unit omnidirectional antenna 4 is connected with the joint 6 that passes base 7; Again by several by locator card 3, unit omnidirectional antenna 4, reflecting plate 5, joint 6 connects single fan antenna of closely forming and then is combined into multi-sector antenna; Cooperation by screw bolt and nut closely is connected base 7 with carriage 8.
