  • Publication number: 20120044120
    Abstract: An antenna for a mobile terminal for improving SAR and HAC characteristics is disclosed. The disclosed antenna may include: a first conductive line electrically connected to a feeding point; a second conductive line separated from the first conductive line at a designated distance and electrically connected to a ground; a third conductive line extending from the second conductive line; and a coupling branch separated from the third conductive line and electrically connected to a ground, where coupling matching and coupling feeding occur between the first conductive line and the second conductive line, and the second conductive line and the third conductive line operate as a radiator. The disclosed antenna can enable impedance matching for a broader band and can improve SAR and HAC characteristics.

  • Publication number: 20110163937
    Abstract: A multi-band antenna using electromagnetic coupling includes a first carrier; a first antenna pattern, which is formed on the first carrier and which includes a power feed part and a radiator part; a second carrier; and a second antenna pattern formed on the second carrier. The first and second carriers are arranged such that the first and second antenna patterns are separated by a particular distance, and the second antenna pattern is not connected to a ground or a power feed line but is formed independently on the second carrier to be fed by electromagnetic coupling with the power feed part of the first antenna pattern. Thus, the multi-band antenna can employ a single power feed setup. Also, the impact on the human body of the frequency signals generated by a terminal can be reduced, and property changes caused by the hand effect and the head effect can be minimized.
