Also include two single layer microstrip wiring boards being respectively arranged in unidirectional two groups of radiation arm groups；Also include the parasitic radiation sheet being located on two single layer microstrip wiring boards.
Wherein, including buckle, described buckle sets two adjacent low-frequency ranges for card and expands radiation detail.
Wherein, described single layer microstrip wiring board includes pcb board and the microstrip circuit being located on pcb board.
Wherein, described single layer microstrip wiring board is fixed with radiating element by plastic cement rivet.
Wherein, described fixture and radiating element clamping.
Wherein, the bottom of described fixture is provided with for the snap fit with reflecting plate clamping.
The invention have the benefit that low-frequency vibrator, include fixture and the radiating element being located on fixture；Described radiating element includes four groups of mutually perpendicular radiation arm groups, and often group radiation arm group includes the first radiation under and the second radiation under being arranged side by side；High band radiation detail all it is extended with between the free end of the second radiation under of the free end of described the first radiation under often the organized radiation arm group with adjacent a group；Described high band radiation detail is also extended with one the 3rd radiation under, and the both sides of the free end of described 3rd radiation under have all downwardly extended low-frequency range and expanded radiation detail；Also include two single layer microstrip wiring boards being respectively arranged in unidirectional two groups of radiation arm groups；Also include the parasitic radiation sheet being located on two single layer microstrip wiring boards.Designed by rational structure, it is provided that, and size is less, simple in construction, can ease of assembly and more firm low-frequency vibrator after assembling；Before and after it, ratio is big, can reach more than 26dB；Its gain is the biggest.

Detailed description of the invention
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not that the practical range of the present invention is confined to this.As shown in Figures 1 to 4, the low-frequency vibrator described in the present embodiment, include fixture 1 and the radiating element 2 being located on fixture 1；Described radiating element 2 includes four groups of mutually perpendicular radiation arm groups, and often group radiation arm group includes the first radiation under 21 and the second radiation under 22 being arranged side by side；Described first radiation under 21 and the second radiation under 22 junction are U-shaped balun；High band radiation detail 23 all it is extended with between the free end of the second radiation under 22 of the free end of described the first radiation under 21 often the organized radiation arm group with adjacent a group；Described high band radiation detail 23 is also extended with one the 3rd radiation under 24, and the both sides of the free end of described 3rd radiation under 24 have all downwardly extended low-frequency range and expanded radiation detail 25；Also include two single layer microstrip wiring boards 4 being respectively arranged in unidirectional two groups of radiation arm groups；Also include the parasitic radiation sheet 6 being located on two single layer microstrip wiring boards 4.Low-frequency vibrator described in the present embodiment, includes buckle 3, and described buckle 3 sets two adjacent low-frequency ranges for card and expands radiation detail 25.Low-frequency vibrator described in the present embodiment, described single layer microstrip wiring board 4 includes pcb board and the microstrip circuit being located on pcb board；Using microstrip coupled feeding classification, pad is few, and intermodulation stability is obviously improved；Low-frequency vibrator described in the present embodiment, described single layer microstrip wiring board 4 is fixed with radiating element 2 by plastic cement rivet 5.Low-frequency vibrator described in the present embodiment, described fixture 1 and radiating element 2 clamping.Low-frequency vibrator described in the present embodiment, the bottom of described fixture 1 is provided with for the snap fit 11 with reflecting plate clamping.Low-frequency vibrator described in the present embodiment, effectively reduces radiating element 2 height, makes antenna volume more miniaturization；Improve before and after antenna than index and cross polarization than index, make network covering property more excellent；High modularization, Integration Design, greatly facilitate production and assembly, and electric property has higher concordance；By Integral-type plastic part mode, radiating element 2 is fixed, the significant increase rejection ability of intermodulation product.
Low-frequency vibrator, includes fixture 1 and the radiating element 2 being located on fixture 1；Described radiating element 2 includes four groups of mutually perpendicular radiation arm groups, and often group radiation arm group includes the first radiation under 21 and the second radiation under 22 being arranged side by side；High band radiation detail 23 all it is extended with between the free end of the second radiation under 22 of the free end of described the first radiation under 21 often the organized radiation arm group with adjacent a group；Described high band radiation detail 23 is also extended with one the 3rd radiation under 24, and the both sides of the free end of described 3rd radiation under 24 have all downwardly extended low-frequency range and expanded radiation detail 25；Also include two single layer microstrip wiring boards 4 being respectively arranged in unidirectional two groups of radiation arm groups；Also include the parasitic radiation sheet 6 being located on two single layer microstrip wiring boards 4.Designed by rational structure, it is provided that, and size is less, simple in construction, can ease of assembly and more firm low-frequency vibrator after assembling；Before and after it, ratio is big, can reach more than 26dB；Its gain is the biggest.
By experimental verification, learn and than averagely all reached more than 26dB before and after it, now take 820MHZ and 855MHZ two frequency measurements its front and back than, as Fig. 3 be 820MHZ frequency measurement its front and back than, front and back ratio is for 26dB；And 855MHZ frequency measurement before and after it than, front and back ratio is for 27dB.
Therefore, the present invention is by relatively simple structure, it is achieved that compare and stable performance before and after relatively big, highly reliable.
The above is only a preferred embodiment of the present invention, therefore all equivalence changes done according to structure, feature and the principle described in present patent application scope or modification, it is included in the protection domain of present patent application.
