For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model is described in further detail.Only this statement, the up, down, left, right, before and after that the utility model occurs in the text or be about to occur, the orientation word such as inside and outside, only take accompanying drawing of the present utility model as benchmark, and it is not to concrete restriction of the present utility model.
The utility model provides a kind of array antenna, comprises base plate, printed wire and printed circuit board base board, and described printed circuit board base board is placed on described base plate by support column, between described printed circuit board base board and described base plate, is air layer; The lower surface of described printed circuit board base board is provided with described printed wire, and described printed wire is positioned on described air layer, under described printed circuit board base board; The upper surface of described printed circuit board base board is provided with printing radiating element, and described printing radiating element is electrically connected to described printed wire.
The utility model adopts suspended mictrostrip as feeding network, and its critical piece comprises four parts such as base plate, air layer, printed wire, printed circuit board base board.In suspended mictrostrip design, because microstrip line adopts accurate TEM ripple, propagate, as the air layer of energy main carriers with as the printed circuit board base board dielectric layer of microstrip circuit carrier, all the impedance of this micro-band is exerted an influence, design very complicated.Although so see that suspended mictrostrip is for some widget, a kind of small size hanging micro-band two way filter as disclosed in CN95240757.4, the feeding network using suspended mictrostrip as whole antenna, there is no disclosed technology.
Design suspended mictrostrip is as the feeding network of antenna, and one of its difficult point is to determine effective dielectric constant.The dielectric constant of air dielectric is generally 1.0, and in embodiment of the present utility model, printed circuit board base board preferentially adopts low-cost RF4 as dielectric layer, and dielectric constant is 4.4.The utility model, by the matching design between base plate, air layer, printed wire and printed circuit board base board, makes effective dielectric constant between 1 to 2, reaches preferably effect.After effective dielectric constant is determined, the designing technique of suspended mictrostrip can be used for reference the design of general medium microstrip line, as impedance matching, power division etc.
It should be noted that, determining of described effective dielectric constant can adopt phase method as the method for extracting equivalence Jie point constant, calculate or test the phase place of the suspended mictrostrip of certain length, then the medium microstrip line identical with a certain length compares, and the dielectric constant of this medium microstrip line of appropriate change, when both phase place is consistent, the dielectric constant of medium microstrip line is effective dielectric constant.
