The present invention relates to an antenna module which can minimize the occupying space in an electronic device, enhancing degrees of freedom to increase efficiency in space utilization, thereby accommodating miniaturization and multi-functionality of the electronic device, and an electronic device having the same. The antenna module includes a flexible substrate, an antenna element having a feeder part, a first fixing part, and a radiation part. The antenna module further includes a feeder line connected to the feeder part having a feeder pad, a first fixing pad connected to the first fixing part, and a pad coupling element. In the invention, signals are processed via interaction between the resonance of the current running through the feeder line to the radiation part and the resonance of the current coming into the pad coupling element.

Antenna module and electronic device using the same

A broadband internal antenna includes a first radiator having a radiation part with one or more coils having different pitch intervals 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. The antenna further includes 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 part for supplying current to the antenna and a 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. Current flowing through the first radiator and current flowing through the strip lines form current paths in different directions to set a certain broadband using mutual Electromagnetic (EM) coupling.

Broadband internal antenna

Disclosed herein is a chip antenna for terrestrial DMB. The chip antenna comprises a dielectric block, a main antenna device formed with conductive patterns in the dielectric block such that a plurality of unit lamination structures of the conductive patterns having a meander line structure in the direction of the Z-axis in an XZ plane are arranged in the direction of the Y axis while adjacent unit lamination structures are connected to each other, forming a lamination structure having the meander line structure in the directions of the Y-axis, and the plurality of lamination structures are arranged in the direction of the X-axis and adjacent lamination structures are connected to each other in the direction of the X-axis to have the meander line structure, and a T-shaped assistant antenna device formed at an upper or lower dielectric layer in the main antenna device.
