Abstract: A method and apparatus for tracking input positions via Electric Field Communication (EFC) are provided. The apparatus includes a plurality of receiving electrodes for EFC and a receiver unit. The receiving electrodes detect strengths of input electric fields. The receiver unit compares the strengths of the input electric fields with each other and generates position information regarding the input electric fields.

Abstract: A method of communicating with a plurality of bands by using an electronic device including a plurality of antennas, an antenna system, and an electronic device is provided. The method includes providing a first or second band signal received via a first antenna to a first transceiver; receiving a first diversity signal for the second band signal via a second antenna and providing the received first diversity signal to a combiner via a signal divider connected to a second transceiver and the combiner; receiving a second diversity signal for the second band signal via a third antenna and providing the received second diversity signal to the combiner; and combining the first diversity signal and the second diversity signal in the combiner and providing the combined signal to a third transceiver connected to the third antenna.
