Abstract
The utility model relates to a small-size dual band antenna which belongs to an external antenna of the high frequency wireless telecommunication equipment terminal and comprises a substrate medium, a high frequency joint and a ground plane; and the small-size dual band antenna is characterized in that three radiators are arranged at the substrate medium, the first radiator and the second radiator are arranged at the lower surface of the substrate medium, and the third radiator are correspondingly arranged at the upper surface of the substrate medium; a RF line used for being connected with the radiator and the high frequency joint is arranged at the lower surface of the substrate medium; a gap is arranged between the first radiator and the second radiator, forming a gap coupling; and groove joints are arranged amongst the first radiator, the second radiator and the third radiator, forming a groove joint coupling. The utility model adopts the gap coupling, reducing the lengths of the radiator and the ground plane, thereby making the structure of the utility model compacter, reducing the volume of the whole antenna, and saving the cost of production.
Description
Technical field:
The utility model relates to a kind of small-sized dual-band antenna, and it belongs to a kind of external antenna of high frequency wireless communication apparatus terminal.
Background technology:
The resonance frequency of traditional microstrip double frequency antenna is by the size decision of radiating surface, and therefore, the design of the radiating surface of existing microstrip double frequency antenna is bigger, and the space that needs when making is bigger; Therefore make that antenna volume increases, processing technology complexity, processing cost are also than higher.
Summary of the invention:
The purpose of this utility model provides a kind of compact conformation, and volume is little, saves the small-sized dual-band antenna of material.
The purpose of this utility model is achieved in that
A kind of small-sized dual-band antenna, it comprises substrate media, high-frequency joint and ground plane, it is characterized in that described substrate media is provided with three radiant bodies, described first radiant body and second radiant body are arranged on the lower surface of substrate media, and described the 3rd radiant body is arranged on the upper surface of the corresponding substrate media in position; Be provided with the radio frequency line that connects radiant body and high-frequency joint at described substrate media lower surface; Between described first radiant body and second radiant body, be provided with the slit, constitute the slit coupling; Be provided with the line of rabbet joint between first radiation, second radiant body and the 3rd radiant body, constitute line of rabbet joint coupling.
Described radiation is four layers of coaxial radio-frequency line.
Described four layers of coaxial radio-frequency line comprise successively by external insulation layer, the grounded metal braid, and insulating barrier and inner wire constitute; Inner wire links to each other with the end of first radiant body.
Described ground plane is made up of three ground planes; Ground plane is provided with the lower surface of substrate media, and another ground plane is provided with the upper surface of substrate media; By the through hole short circuit, ground plane is arranged on the other end of the close high-frequency joint of substrate media between ground plane and the ground plane, and and ground plane between by the through hole short circuit.
The utility model reduces the length of radiant body owing to adopted the slit coupling; And reduced the length of ground plane, and make overall structure of the present utility model compact more, dwindled the volume of entire antenna, the production cost of saving.Of the present utility model returning is lost in 2400MHz-2500MHz; 5100MHz-5800MHz is all less than-10dB; Meet general use standard.
