Abstract:
1. A broadband internal antenna, comprising: a first radiator having a radiation part in which one or more coils having different pitch intervals are connected in series to each other; and a second radiator having at least one conductive strip line arranged parallel to a longitudinal direction of the first radiator, a connection part to which an end of the at least one conductive strip line is connected, to which a first end of the first radiator is attached and in which a power feeding part for supplying current to the antenna and a ground part for grounding the antenna are formed, and an attachment pad to which a second end of the first radiator is attached and from which current is drawn; wherein current flowing through the first radiator and current flowing through the strip lines form current paths in different directions, thus setting a certain broadband using mutual Electromagnetic (EM) coupling.
