DUAL-BAND MONOPOLE COUPLING ANTENNA

摘要

A dual-band monopole coupling antenna is disclosed, which comprises: a first radiation part, configured with a frame and an extension section while being disposed on a surface of a substrate; a second radiation part, disposed on the surface of the substrate at a position neighboring to the first radiation part for enabling a coupling effect between the two, allowing the second radiation part to be used as an extension of the first radiation part, and thus adjusting the operation frequency, impedance and impedance matching accordingly; a signal ground section, disposed coupling to the second radiation part; a signal feed-in section, disposed on the surface at a position neighboring to the signal ground section while coupling to the first radiation part; a ground, disposed coupling to the second radiation part; and a dielectric layer, disposed at an non-conductive area arranged between the first radiation part and the second radiation part.

1. A dual-band monopole coupling antenna, comprising:
a first radiation part, being disposed on a surface of a substrate; a second radiation part, disposed on the surface of the substrate at a position neighboring to the first radiation part for enabling a coupling effect between the second radiation part and the first radiation part so as to allow the second radiation part to be used as an extension of the first radiation part, and thus for enabling the overall operation frequency, impedance and impedance matching of the dual-band monopole coupling antenna to be adjusted accordingly; a signal ground section, disposed on the surface of the substrate while having an end thereof to connect to the second radiation part and another end thereof to connected to a signal feed-in line; a signal feed-in section, disposed on the surface of the substrate at a position neighboring to the signal ground section while coupling to the first radiation part; a ground, disposed on the surface of the substrate while coupling to the second radiation part; and a dielectric layer, disposed at an non-conductive area; wherein, the first radiation part is designed to operate at a first frequency, while the second radiation part is designed to operate at a second frequency.
