The antenna device includes a high-band antenna element and a low-band antenna element that are connected to a common feed point, an antenna-shortening inductor that is connected to between the low-band antenna element and the feed point, and a capacitor that is connected to the antenna-shortening inductor in parallel.

The present disclosure relates to an antenna module and a mobile terminal having the same, and the antenna module may include a conductive member, a first conductive arm formed at one side of the conductive member to form a first loop along with the conductive member so as to implement a first resonant frequency, a second conductive arm formed at the other side of the conductive member to form a second loop along with the conductive member so as to implement a second resonant frequency different from the first resonant frequency, a first feeding portion formed adjacent to the first conductive arm to feed the first conductive arm and conductive member, and a second feeding portion formed adjacent to the second conductive arm to feed the second conductive arm and conductive member.

The present invention provides a technique to optimize and/or extend the length of an antenna arm or antenna ground plane for communications components contained in a printed circuit board (PCB) within a communications device. In an embodiment of the invention, an antenna arm or ground plane extension is provided as part of a lanyard for holding the communications device. For example, the lanyard comprises a cord passed around the neck, shoulder, or wrist. The cord comprises an electrical conductor coupled to the communications components. The electrical conductor serves as the antenna arm or ground plane. The length of the PCB need not to be extended to improve antenna efficiency and gain. Ideally, the lanyard antenna extension is ideally coplanar with the PCB. Careful lanyard material selection determines the most efficient and practical wavelength or resonance length of the antenna.
