For example, the printed circuit board 120 may include a communication circuit 130, a processor 140 (or a communication processor), a memory, an application processor (AP), or the like. In this document, the printed circuit board 120 may be referred to as a main board, or a printed board assembly (PBA).

The communication circuit 130 may be electrically connected to each of the first antenna 116-1 through the fourth antenna 116-4. For example, the communication circuit 130 may be electrically connected to each of the first antenna 116-1 through the fourth antenna 116-4 through a designated wire, a wire, and the like. In this document, the communication circuit 130 may be referred to as a wireless communication circuit.

The processor 140 may be electrically connected to the communication circuit 130. The processor 140 may sweep the phase of at least one of the first antenna 116-1 through the fourth antenna 116-4 through the communication circuit 130. [ For example, the processor 140 may transmit a first signal (or a transmitted signal) to the base station 10 via the communication circuit 130 and the plurality of antennas. At this time, the processor 140 may receive a second signal (or a reflected transmission signal) that is fed back through the communication circuit 130. In this document, the second signal may refer to a signal that is reflected from a particular element (e.g., coupler) and then back into the processor 140 as the first signal passes through the communications circuitry 130.

In this document, the beam pattern may mean the electric field intensity of a signal radiated from at least one of the first antenna 116-1 to the fourth antenna 116-4.

According to the electronic device according to the comparative example, electromagnetic waves can be generated in the process of transmitting a signal through the antenna. In particular, since the multiple transmission antennas include a plurality of antennas, the specific absorption rate (SAR) may be significantly increased as compared with the case of using a single antenna. However, according to an embodiment of the present invention, the phase of at least one of the first antenna 116-1 to the fourth antenna 116-4 may be swept so as to control the direction of the beam pattern to be away from the body . Accordingly, the amount of electromagnetic waves generated by the first antenna 116-1 through the fourth antenna 116-4 absorbed by the body can be reduced.

The battery 150 can convert chemical energy and electrical energy in both directions. For example, the battery 150 may convert chemical energy into electrical energy and supply the converted electrical energy to various components or modules mounted on the display 160 and the printed circuit board 120. Alternatively, the battery 150 may convert electrical energy supplied from the outside into chemical energy and store the same.

The operation of transmitting / receiving a signal through the first antenna 116-1 can be similarly applied to the second antenna 116-2 to the fourth antenna 116-4. I will explain it as a standard.

The first coupler 131-1 may monitor the first signal when the first signal (or transmission signal) is transmitted to the base station 10 through the first antenna 116-1. For example, the first coupler 131-1 may monitor whether the first signal to be transmitted by the processor 140 has been transmitted and / or whether a first signal having an appropriate amount of power has been transmitted, and so on.

In another embodiment, the first coupler 131-1 may transmit a second signal (or a feedback signal) reflected from the first signal through the first coupler 131-1 to the transceiver 134. For example, when the processor 140 includes a transceiver 134, a first power amplifier 133-1, a first duplexer 132-1, a first coupler 131-1, and / or a first antenna 116-1, The first coupler 131-1 may transmit the second signal to the transceiver 134 when transmitting the first signal to the base station 10. [

The first duplexer 132-1 can separate the transmitting and receiving frequencies. For example, the first duplexer 132-1 separates the frequency of a signal received through the first antenna 116-1 and the frequency of a signal transmitted through the first antenna 116-1, Interference between signals can be prevented.

The first power amplifier 133-1 amplifies the first signal and transmits the amplified first signal to the first duplexer 132-1 and the first coupler 131-1, Lt; / RTI >

The transceiver 134 may include a modulation section 134m, a power detection section 134p, and / or a demodulation section 134d.

The demodulation unit 134d may demodulate the signal received by the electronic device 100 through the first antenna 116-1. For example, the demodulation unit 134d can demodulate the second signal received from the power detection unit 134p. The demodulation unit 134d may transmit the demodulated second signal to the processor 140. [ The processor 140 may measure the parameters based on the demodulated second signal. For example, the processor 140 may measure I / Q values of each of the first antenna 116-1 to the fourth antenna 116-4 based on the second signal demodulated by the demodulator 134d. The I / Q value in this document means data used by the processor 140 to determine the state of the first antenna 116-1 through the fourth antenna 116-4 (e.g., the gain of the antenna) can do.

The processor 140 may sense whether the body is proximate to the electronic device 100 based on the measured parameters. For example, the processor 140 may detect whether a user's hand has contacted the electronic device 100.

3A shows a constellation diagram of a first antenna according to an embodiment. FIG. 3B illustrates a constellation diagram of a second antenna according to an embodiment. 3A and 3B show constellations of the antennas 116-1 and 116-2 of FIG.

3A and 3B, the processor 140 may measure I / Q values for a second signal (or a feedback signal) reflected from the couplers 131-1 and 131-2. The measured I / Q value may be divided into a real value (I-Value) and an imaginary value (Q-Value). The real and imaginary values are combined to form a complex value, And can be expressed in the form of constellations 310 and 320 in FIGS. 3A and 3B.

The processor 140 may compare the measured I / Q value with a mapping table stored in the memory to detect proximity of the body. The mapping table is a table including a magnitude value, a phase value, an antenna gain, and proximity of an external object corresponding to I / Q values, and can be defined as shown in Table 1 below. have. The external object may refer to an object that is contacted or coupled to electronic device 100, such as an ear jack, body, USB cable, and the like.

According to one embodiment, the processor 140 may compare the constellations shown in FIGS. 3A and 3B with Table 1 to detect proximity to the body. In the case of the first antenna 116-1, the processor 140 can sense that the jack is connected to the electronic device 100 since the I / Q value in the constellation is P1. In the case of the second antenna 116-2, since the I / Q value is P24 in the constellation diagram, the processor 140 can detect that the user's hand is in contact with the electronic device 100. [ In this embodiment, since the external object sensed through the first antenna 116-1 is an ear jack, the electronic device 100 may not sweep the phase of the antennas. On the other hand, since the external object sensed through the second antenna 116-2 is the human body, the electronic device 100 can sweep the phase of the antennas. In this case, the electronic device 100 may sweep the phase of the antennas so that the direction of the beam pattern is formed in a direction away from the body. Since the direction of the beam pattern is formed in a direction away from the body, the absorption rate of the electromagnetic wave of the body can be reduced.

The second sweep zone	De-Activation	Activation (Body)	De-Activation	Activation (Body)
Third sweep zone	De-Activation	Activation (Body)	De-Activation	Activation (Free Space)

For example, referring to Table 2, the electronic device 100 deactivates the first antenna 116-1 and the third antenna 116-3, and the second antenna 116-2 and the fourth antenna 116-4 may be activated. In this case, the electronic device 100 may sweep the phases of the second antenna 116-2 and the fourth antenna 116-4 such that the direction of the beam pattern is away from the body. For example, in the first sweep zone, the electronic device 100 can detect that the body is not in contact with the second antenna 116-2, but can detect that the fourth antenna 116-4 is in contact with the body. Accordingly, the electronic device 100 may sweep the phase of the second antenna 116-2 and / or the fourth antenna 116-4.
