[embodiment]
The present invention is further illustrated below in conjunction with drawings and Examples:
See also shown in Figure 2ly, a kind of TD-SCDMA compact intelligent antenna system is made up of following each several part:
Eight antenna array units 51,52,53,54,55,56,57,58, there are 8 radiating elements 31 in each antenna array unit 51～58; A reflecting plate 21 as the reflector of radiating element 31, is positioned at the back of described radiating element 31, for radiating element 31 installing on it, adopts conduction to be connected or the capacitive coupling connection between described radiating element 31 and the reflecting plate 21; One group of calibration network 11 is installed on the reflecting plate 21, and its part port is connected with above-mentioned array element row 51,52,53,54,55,56,57,58 respectively, and other port is connected with base station system, is used to carry out system calibration.
Between described adjacent two bays dividing plate is set, adopts conduction to be connected between dividing plate and the reflecting plate 21 or the capacitive coupling connection.
Can be parallel distribution mode as shown in Figure 2 and put for the relative position between the described antenna array unit 51,52,53,54,55,56,57,58, also can adopt Fig. 3, Fig. 4 and the mode that is interspersed shown in Figure 5 perhaps are the mixing of above-mentioned distribution mode.
For the purpose of optimizing performance, between adjacent two antenna array units, dividing plate 41,42,43,44,45,46,47 is set respectively, as shown in Figure 6, adopt conduction to be connected between dividing plate 41,42,43,44,45,46,47 and the reflecting plate 21 or the capacitive coupling connection.
Among the present invention, adjacent two antenna array units 51～58 spacing side by side (shown in d among Fig. 3) in the horizontal direction can be made as 1/3 to 1/4 operation wavelength on the basis of balance dimension and performance, this measure has reduced its cross-sectional area about 40% on the basis of traditional intelligence antenna, so make TD-SCDMA smart antenna size and traditional base station antenna size comparability intend, to obtain the height approval in market, for the sizable application of smart antenna is cleared away the obstacles.
But antenna array unit 51～58 spacing in the horizontal direction can cause the increase of mutual coupling when reducing, in order to reduce to adopt the distribution feed that does not wait phase between the radiating element 31 of each antenna array unit 51～58 owing to mutual coupling strengthens the mis-behave that brings.The described feed that distributes mutually that do not wait is made of jointly two-part summation, first PHASE DISTRIBUTION partly be from same array antenna row unit first radiating element to the phase place of last radiating element lag or lead successively, form linear PHASE DISTRIBUTION, and the phase difference of adjacent two radiating elements is in 25 °～45 ° scopes, for example get 33 °, described first PHASE DISTRIBUTION is not wait the principal character that distributes mutually, realizes the high-isolation between array; Second PHASE DISTRIBUTION partly is the distribution of an optimization perturbation, for not waiting accidental quality that distributes mutually, is mainly used in the wave beam forming that cooperates corresponding amplitude distribution realization antenna; The isolation that improves between antenna array unit for the realization decoupling also can adopt the mode of being interspersed put its antenna array unit, or adopts the mixed form that is interspersed with parallel distribution dual mode.
Described calibration network 11 both can be installed in the front of reflecting plate 21, also can be installed in the back side of reflecting plate.In order to reduce the influence of 31 pairs of calibration networks 11 of radiating element, generally described calibration network 11 is placed semi-enclosed shielding construction simultaneously.
The present invention makes the traditional intelligence antenna be able to further miniaturization, above embodiment only in order to the explanation the utility model and and the described technical scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technical scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the middle of the claim scope of the present utility model.
