Description
Technical field
The utility model relates to a kind of unipole antenna.
Background technology
In miniaturized communication products (as wireless Wireless Router, Intelligent wearable electronic equipment) or built-in antenna communication products, antenna volume affects the configuration of integral member.So antenna volume is less, be more conducive to the convenience of integral member configuration, also more can reduce the volume of communication products, but the volume of antenna and communication products is too small, the length poor effect on the ground of antenna, can have a strong impact on the usefulness of antenna.
So, be necessary that a kind of new unipole antenna of design is to solve the problems of the technologies described above.
Utility model content
The purpose of this utility model there are provided a kind ofly has the unipole antenna improving earthing effect.
For realizing aforementioned object, the utility model adopts following technical scheme: a kind of unipole antenna, in order to be arranged on a communication equipment, it comprises the first radiation arm, one second radiation arm, a junction connecting first, second radiation arm and a sheet metal, described unipole antenna also comprises the ground coupling piece be connected with connecting portion, described sheet metal contacts with ground coupling piece and connecting portion, and described sheet metal contacts with communication equipment and electrically conducts.
As further improvement of the utility model, described sheet metal is provided with the shell fragment be pressed on the circuit board of communication equipment.
As further improvement of the utility model, described first radiation arm, the second radiation arm, coupling arm and connecting portion observe along the vertical direction and be respectively arc.
As further improvement of the utility model, described connecting portion comprises first, second relative end, first end have to downward-extension one first brace and bend the first contact chip of extension to the inside, described first radiation arm extends from the first brace bottom form along being parallel to connecting portion direction.
As further improvement of the utility model, described second end has the second brace to downward-extension, and the second radiation arm forms along being parallel to the extension of connecting portion direction from the second brace bottom.
As further improvement of the utility model, described second radiation arm is positioned at the below of the first radiation arm, and separates between the upper and lower.
As further improvement of the utility model, described ground coupling piece together with the circuit board of communication equipment to improve the problem on the ground of unipole antenna.
The utility model unipole antenna increases by a ground coupling piece, and ground coupling piece is electrically connected by sheet metal and connecting portion, improves the earthing effect of unipole antenna, improves the usefulness of unipole antenna.
