Abstract: The present invention relates to a method for shortening an average time applied when an influence of electromagnetic waves of a base station on a human body is evaluated around a mobile communication base station. The invention compares uncertainty caused by repeated measurements with the result of on-the-spot measurements by targeting a plurality of base stations, performs measurements for six minutes at a random measurement point for obtaining a whole-body average, and considers that a shorter measurement time would be sufficient rather than the six minutes if a standard deviation is less than or equal to a certain level, for example, 0.4 dB when a six-minute average value is compared with an average value of a shorter time other than six minutes.

Abstract: The present invention relates to a structure of an antenna and its shielding structure for a mobile phone which may significantly reduce the hazardous electromagnetic wave transmitted to the user's body. The present invention arranges a monopole antenna inside of the mobile phone housing, and installs an electromagnetic wave absorber between the antenna and the circuit board. The electromagnetic wave absorber can absorb the electromagnetic wave reflected form conductive plate constituting the circuit board. Thus, the adverse effect of the reflected electromagnetic wave to the performance of antenna is prevented and the amount of the electromagnetic wave to which the users is exposed can be significantly reduced as well.

Abstract: PURPOSE: An antenna is provided to obtain high isolation by attenuating a transmission signal which does not pass through an object. CONSTITUTION: A first antenna(2) and a second antenna(3) are vertically arranged with each other. A third antenna(4) and a fifth antenna(6) are symmetrical based on the plane formed by the first and second antennas. The third antenna and a fifth antenna are vertical to the first antenna. The inner cores of a feeding connector of the third and fifth antennas are arranged in the opposite direction. A fourth antenna(5) and a sixth antenna(7) are symmetrical based on the plane formed by the first and second antennas. The fourth antenna and the sixth antenna are horizontal to the first antenna.

Abstract: PURPOSE: A wireless power transmission device and method for reducing radiated power of a magnetic resonator are provided to transmit energy by selecting a frequency having relatively low radiated power. CONSTITUTION: A signal generator(102) generates a frequency signal used for wireless energy transmission from general commercial AC powder. A power amplifying unit(104) amplifies the frequency signal. A signal detection unit(106) transfers the amplified signal to a magnetic resonator for wireless energy transmission and detects a radiated signal caused by the magnetic resonator. A standing-wave ratio calculation unit(108) calculates a standing-wave ratio from the detected signal. A control unit selects the frequency having the lowest standing-wave ratio using the standing-wave ratios calculated by the standing-wave ratio calculation unit.
