Abstract: A portable communication device is Provided for supporting multiple different communication networks. The portable communication device includes an antenna configured to receive a first signal of a first frequency band corresponding to a first cellular network, and a second signal of a second frequency band corresponding to a second cellular network; a first communication circuit electrically connected to the antenna and corresponding to the first cellular network; a second communication circuit electrically connected to the antenna and corresponding to the second cellular network; a distributor configured to electrically connect the antenna to the first communication circuit and the second communication circuit; a first low noise amplifier (LNA) connected between the distributor and the first communication circuit; and a second LNA connected between the distributor and the second communication circuit. While one of the first communication circuit and the second communication circuit is not driven, the other communication circuit is configured to be driven.
