An electronic device is provided. The electronic device includes a plurality of antennas, a radio frequency (RF) circuit configured to electrically connect with the plurality of antennas, and a processor. The plurality of antennas include a first main antenna, a first sub-antenna, a second main antenna, and a second sub-antenna. The processor controls the RF circuit to operate in a first mode of receiving a signal using the first main antenna and the first sub-antenna. The processor controls the RF circuit to operate in a second mode different from the first mode to receive the signal based on a signal state.

Method and apparatus for selecting reception antenna set of user terminal

An electronic device is provided. The electronic device includes a plurality of antennas and a communication circuit configured to electrically connect with at least one of the plurality of antennas, wherein the communication circuit is configured to obtain information of a level of a transmit power and transmit a signal based on a designated antenna among the plurality of antennas if the level of the transmit power is less than a level, determine an antenna for signal transmission among the plurality of antennas if the level of the transmit power is greater than or equal to the level, and perform an antenna switching operation of selecting the determined antenna.

Method for selecting transmit antenna and electronic device for supporting the same

The present invention provides a magnetoelectric material in which an electric property is capable of being controlled by a magnetic field or a magnetic property is capable of being controlled by an electric field, and a method of manufacturing the same. Particularly, the present invention provides a magnetoelectric material in which a distance between magnetic ions interacting with each other is controlled by using non-magnetic ions or alkaline earth metal ions, and a method of manufacturing the same.

Magnetoelectric material and method of manufacturing the same

Disclosed herein is a method and system for measuring magnetoelectric susceptibility. The system includes a magnet supplying a DC magnetic bias to a magnetoelectric sample, an AC drive coil applying an AC magnetic field to the magnetoelectric sample, a charge amplifier amplifying an electric charge signal of the magnetoelectric sample oscillating by the AC magnetic field, and a phase sensitive detector detecting the voltage signal produced by the charge amplifier while supplying induction current to the AC drive coil. Accordingly, it is possible to provide a highly sensitive system for measuring magnetoelectric susceptibility, which is essential for research on multiferroic and magnetoelectric bulk and thin film materials at room temperature, and can also operate in the physical property measurement system (PPMS, manufactured by Quantum Design Co., Ltd.) for measurements under low temperature and high magnetic field environments.

Magnetoelectric susceptibility measurement method and the system thereof

A luminance/chromaticity signal separation circuit for a composite video signal, consisting of one-line delayers, inverters, adders, multipliers, low-pass filters, subtractors, comparators, band-pass filters, and line comb filters, capable of exactly separating a luminance signal and a chromaticity signal by selectively using output signals which are adapted to vertical luminance variations.
