Broadband internal antenna for mobile communication terminal, has radiator with conductive stripline through which current flows to form current paths in different directions to set certain broadband using electromagnetic coupling

摘要

The antenna has a radiator (41) with a radiation part with multiple coils which includes different pitch intervals that are connected in series. Another radiator (42) with a conductive strip line is arranged parallel to a longitudinal direction of the former radiator. A current flowing through the strip lines form current paths in different directions to set a certain broadband using mutual electromagnetic (EM) coupling.
