BROADBAND ANTENNA USING TUBULAR MATCHING

摘要

The present invention relates to a broadband antenna using tubular matching. The antenna comprises an impedance-matching and electricity-supplying part and a first emitting member electrically connected to the impedance-matching and electricity-supplying part. Here, the impedance-matching and electricity-supplying part comprises a first matching member of a predetermined length which is connected to the earth and a second matching member which is connected to an electricity-supply point, and the second matching member has a structure such that it surrounds the first matching member.
