Abstract: A portable communication device includes a processor positioned in a first printed circuit board; a communication circuit; and an antenna module. The antenna module includes a second printed circuit board; a first antenna and a second antenna positioned in the second printed circuit board; a first transmission-reception circuit positioned in the second printed circuit board. The first transmission-reception circuit comprises a power amplifier for amplifying a signal to be transmitted through the first antenna, and a first low noise amplifier for amplifying a signal received through the first antenna. The power amplifier forms a portion of a transmission path electrically connected with the communication circuit and the first antenna. The first low noise amplifier forms a portion of a first reception path electrically connected with the communication circuit and the first antenna. The transmission path or the first reception path in the first transmission-reception circuit is selectively provided by the communication circuit. The portable communication device also includes a first reception circuit positioned in the second printed circuit board, wherein the first reception circuit does not comprise a power amplifier for amplifying a signal to be transmitted through the second antenna, and comprises a second low noise amplifier for amplifying a signal received through the second antenna, the second low noise amplifier forming a portion of a second reception path electrically connected with the communication circuit and the second antenna.
