Description
Technical field
The utility model relates to a kind of inverse-F antenna, is a kind of couple feed inverse-F antenna specifically.
Background technology
Along with the development of WLAN communication technology, more and more higher to the requirement of its built-in aerial, all need little, the lightweight miniature antenna of volume.Because inverse-F antenna has possessed miniaturized advantage, be therefore widely used in all kinds of WLAN devices.But inverse-F antenna has very strong directivity in wireless coverage, horizontal plane covers uneven, causes omnidirectional's poor-performing of antenna, can not adapt to the requirements at the higher level of antenna.
Summary of the invention
For the deficiency of omnidirectional's poor performance of inverse-F antenna in prior art, the utility model provide a kind of structure simple, can effectively improve antenna direction deviation in roundness, improve the couple feed inverse-F antenna of omnidirectional's performance.
The technical solution adopted in the utility model is: a kind of couple feed inverse-F antenna, comprise base plate, insulating cover and antenna body, antenna body is hermetically sealed on base plate through insulating cover, its technical characterstic is that described antenna body comprises a left side, right radiant body, left, right radiant body is opposing to be symmetrical arranged, left radiant body comprises left radiator, couple feed sheet, feeder pillar and earthing rod, left radiator outer side edges insulating supporting is on base plate, in the middle part of left radiator, below is provided with the couple feed sheet supported through feeder pillar, couple feed sheet and left radiator parallel coupling are arranged, feeder pillar is connected in the feeding interface below base plate, left radiator inner side edge to be supported on base plate and through base plate to external ground through earthing rod, right radiant body comprises right radiator, coupling grounding sheet and earth brace, right radiator outer side edges insulating supporting is on base plate, in the middle part of right radiator, below is provided with the coupling grounding sheet supported through earth brace, coupling grounding sheet and right radiator parallel coupling are arranged, earth brace is connected in the ground interface below base plate, and right radiator inner side edge is supported on floor through earthing rod, the left radiant body of earthing rod, feeder pillar and the left radiator composition structure of falling F, the right radiant body of earthing rod, earth brace and the right radiator composition structure of falling F.
Further, described left and right radiator is parallel to base plate setting.
Further, described left and right radiator includes horizontal radiation section and bending radiant section, couple feed sheet is provided with the horizontal segment corresponding with left radiator level, bending radiant section and bending section, and coupling grounding sheet is provided with the horizontal segment corresponding with right radiator level, bending radiant section and bending section.
Again further, described insulating cover contour structures is parallel to left and right radiator.
Adopt above technical scheme, the beneficial effects of the utility model are:
The inner side edge of the left and right radiator of earthing rod difference support and connection 1, in the left and right radiant body centre position of the structure of falling F, short circuit grounding point is adopted in the inverse-F antenna structure of low profile, effectively improve the deviation in roundness of antenna pattern, reduce antenna profile height further;
2, left radiant body adopts coupling feed tab to carry out couple feed to left radiator, improves the efficiency of antenna; The right radiant body simultaneously arranged with the symmetric position of antenna short circuit point adopts coupling grounding sheet by right radiant body coupling grounding, can improve the direction deviation in roundness of antenna further.
