[embodiment]
Be further described the present invention below in conjunction with accompanying drawing and exemplary embodiment, wherein identical in accompanying drawing label all refers to identical parts.In addition, if the detailed description of known technology is for illustrating that feature of the present invention is unnecessary, then omitted.
With reference to Fig. 1-2, broadband dualpolarization radiation unit of the present invention 100 (call in the following text " radiating element); comprise annular base 20, four couples of feed Ba Lun 30 extended radially from described annular base 20 edge centered by the center of annular base 20, enclose two electrode couple 401,402,403,404 be arranged on described feed Ba Lun 30, and by coupled structure that the radiation arm of adjacent two dipoles couples together.
Described each dipole comprises two radiation arms, and for dipole 401, it comprises two radiation arms 401a, 401b, and described radiation arm comprises first end and the second end, and such as radiation arm 401b comprises first end 401b1 and the second end 401b2.
Described coupled structure comprises coupling piece 50, second end of the radiation arm of described adjacent two dipoles is of coupled connections by coupling piece 50 or is directly connected, further, the second end of the adjacent radiation arm of the dipole that the second end of a radiation arm of at least one dipole is adjacent with another is connected by coupling piece.
By adopting coupled structure such as coupling piece 50 to be connected by the radiation arm of adjacent two dipoles, in a disguised form adding the resonance length of radiation arm, being also namely equivalent to the length extending radiation arm.In other words, when originally needing the radiation arm of equal length to carry out signal radiation, connect two radiation arms owing to have employed coupling piece, the physical length of the radiation arm be connected with coupling piece can shorten to a certain extent, thus reduces the volume of whole radiating element.
As everyone knows, the bandwidth of antenna is relevant with impedance, and in order to reach enough bandwidth, the imaginary part (i.e. reactance) of General Requirements impedance is the smaller the better, even for the ease of coupling, wishes that the reactance of radiating element is zero.Adopt coupled structure to be coupled together by the radiation arm of adjacent two dipoles, the imaginary part of impedance can be made simultaneously slack-off with the growth of frequency, thus ensure that radiating element has wider bandwidth, namely reach the demand in broadband.
The first end (such as 401b1) of described radiation arm is connected with feed Ba Lun 30, and its second end (such as 401b2) is then away from the described feed Ba Lun 30 be connected with first end.All described radiation arms are all straight-arm, and all radiation arms enclose a class loop configuration jointly.
Particularly, four described dipoles are set gradually on annular base 20 by feed Ba Lun 30, enclose infundibulate closing structure, four dipoles take radiation symmetric as structural environment and arrange around same geometric center (i.e. the center of annular base 20), thus present the radiating surface of an encirclement shape by the radiation arm of each dipole.
