Plane super wide band coupling antenna

摘要

A plane super wide band coupling antenna comprises an isolating substrate for installing with a metal thin film layer by printing; a first radiating portion being a metal thin film layer printed upon the isolating substrate; the first radiating portion having a coupling section and being extended with a feeding point; a second radiating portion being a metal thin film layer printed upon the isolating substrate; the second radiating portion extending from a ground portion on the isolating substrate and being a bended structure; the second radiating portion being formed with gaps with the first radiating portion; the ground portion being formed by a metal thin film layer; one end thereof being electrically connected to the second radiating portion; a signal feeding wire being a coaxial cable; and the main signal wire of the signal feeding wire being electrically connected to the feeding point of the first radiating portion.
