ANTENNA DEVICE USING LINK LINE

摘要

Disclosed is an antenna device using a link line. The disclosed antenna device comprises: a first radiation body; a second radiation body having the same structure as the first radiation body; a third radiation body located between the first and second radiation bodies; a first link line connecting the first radiation body and the third radiation body; and a second link line connecting the second radiation body and the third radiation body, wherein the first and second radiation bodies are multi input multi output (MIMO) radiation bodies, and the first to third radiation bodies have at least one resonant frequency in the same frequency band. According to the disclosed antenna device, a good isolation can be obtained among at least three antennas and a good isolation can be obtained among heterogeneous antennas having different structures from each other.
