Problems solved by technology

Chinese patent 200410028003.x discloses a method of real-time calibration using a filter coupler, which can be used not only in planar arrays, but also in circular arrays. However, the passive devices required by this method are too complicated and difficult to implement. certain degree of difficulty
Chinese patent 20051005167.2 pointed out the method of adding a whole metal strip between each channel to form an electric wall, although this method can improve the isolation of the antenna, adding the whole metal strip adds difficulties to the debugging of the standing wave of the antenna
[0007] Chinese patent 02265177.2 discloses the use of a microstrip circuit board as the radiation unit of the smart antenna, and the antenna feed network and radiator are printed on the same circuit board. Although the consistency and reliability are increased, the height of the antenna is also greatly improved. increase, which adds difficulties to the mechanical performance design of the antenna

Embodiment Construction

[0023] As shown in Figure 1, the ultra-thin smart antenna that is used for time division system of the present invention is vertically welded on the feeder that has microstrip circuit to form by calibration network 22, reflecting plate 21, antenna cover 25, feeder network 18 and printing vibrator 19 On the network 18, antenna arrays 10, 11, 12, 13, 14, 15, 16, 17 are formed; the antenna arrays are evenly spaced and installed on the reflector 21, and the antenna arrays are connected with the calibration network 22 through cables 24, 25 to form an antenna subject. At the same time, a metal strip 20 with a certain length is arranged between adjacent antenna arrays, and the metal strip 20 is fixed on the reflection plate 21 through a medium. The antenna also includes a bottom plate, which has the same size as the reflection plate 21, and is a metal plate with a frame around it, and the bottom plate is installed with the reflection plate 21 through a connecting piece. The array of...

Abstract

Ultrathin intelligent antenna in use for time-division system includes feeding net, printed vibrator, calibration net, reflecting plate, and antenna outer cover. Characters are that the printed vibrators welded to the feeding net composed of microstrip circuit vertically constitute antenna array fixed on the reflecting plate. Through cable, antenna array connected to the calibration net constitutes main body of antenna. Connection cable for antenna array and calibration net is coaxial cable with SMA adaptor at two ends. There is certain proportional relation between distance from array to array and wavelength. The invention solves issue of unstable antenna performance existed for long time. Features are: lowering thickness of antenna, raising consistency and mechanical properties of antenna produced.
