Abstract
The utility model discloses a directional antenna which comprises a reflector, an isotropic antenna and a fixing device, wherein the isotropic antenna is connected with the reflector through the fixing device, and the reflector can be a reflecting rod or a reflecting plate. The directional antenna of the utility model adjusts the width of the wave beam at the horizontal plane to the required angle in the form of the isotropic antenna and the reflector, and the wave beam at the vertical plane is controlled by the wave beam of the isotropic antenna. Thus, the beam control of the horizontal plane and the vertical plane is separated. As long as the distance between the reflector and the isotropic antenna is adjusted, the required index can be achieved to make the debugging process more convenient and rapid.
Description
Technical field
The utility model relates to the antenna of mobile communication base station field, relates in particular to a kind of directional antenna that is used for the mobile communication base station.
Background technology
Conventional mobile communication base station directional antenna comprises plate antenna, parabolic antenna, corner reflector antenna etc., wherein plate antenna mostly is a kind of fully closed with the antenna of metallic plate as reflecting plate with radome, some radiating elements are distributed on the reflecting plate, by by the air microstrip line, strip line, the feeding network that wiring board or cable are formed is given each radiating element feed, control its phase place and amplitude, directional antenna with other type is the same, plate antenna has its applicable scope, but there is the processing technology complexity, the cost height, be difficult for debugging and wait comparatively distinct issues, therefore, under the non-situation that must use plate antenna, consider with a kind of manufacturing process and debugging simple, it also is the problem that the insider paid close attention to that the antenna that cost is low substitutes its application.
The utility model content
The directional antenna that technical problem to be solved in the utility model provides a kind of manufacturing process and debugging is simple, cost is low, can replace plate antenna to use under specific circumstances.
For achieving the above object, the technical solution of the utility model is: a kind of directional antenna, comprise reflector, omnidirectional antenna and fixture, and described omnidirectional antenna is connected with described reflector by described fixture.
Described reflector is a reflecting plate, described fixture comprises positioning fixture, an above locator card, described positioning fixture clamps the omnidirectional antenna stationary pipes and is fixed on the reflecting plate, described locator card is fixed in the other end of omnidirectional antenna on the reflecting plate, the electrical property of the position-adjustable directional antenna by changing positioning fixture and locator card.
Described reflecting plate is provided with the hole of leaking out more than, to strengthen the wind resistance of antenna.
Described reflector is to reflect bar more than one, described fixture comprises upper end fixed head, lower end fixed head, described lower end fixed head and upper end fixed head are individually fixed in the stationary pipes position and the other end of omnidirectional antenna, described reflection bar is fixed between upper end reflecting plate and the lower end reflecting plate, be arranged in omnidirectional antenna around.
Directional antenna described in the utility model, the form that adopts omnidirectional antenna to add reflector (reflector can be reflection bar or reflecting plate) is adjusted to the horizontal plane beamwidth angle of 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, as long as the index that the distance between accommodation reflex device and the omnidirectional antenna just can obtain requiring makes debug process convenient and swift.
