    摘要: Provided is a method and apparatus improving a deterioration of a gain flatness and a phase characteristic that may be incurred while a baseband signal is transformed into a immediate frequency (IF) signal and a radio frequency (RF) signal in a broadband wireless communication system. A sub-band extractor may divide the broadband signal into multiple sub-band signals, may pre-compensate for a gain and a phase delay of each sub-band signals in the baseband, and may combine the pre-compensated sub-band signals into the single broadband signal and thus, the deterioration of the gain flatness and a phase delay flatness that may be incurred while the broadband signal is transformed into the IF signal and the RF to signal, may be improved.

    摘要: Disclosed is an apparatus for measuring sizes of a human body, such as the length of an arm, the size of a waist and the width of a shoulder, in the state that a person does not take off its clothes, using millimeter waves. The apparatus includes a plurality of millimeter-wave transmission/reception units, a rotation unit and a digital signal processing unit. The plurality of millimeter-wave transmission/reception units are arranged in a circular shape around an object to be measured, transmit a millimeter wave to the object to be measured, and receive a signal reflected or scattered by the object to be measured. The rotation unit rotates a circular structure in which the plurality of millimeter-wave transmission/reception units are arranged. The digital signal processing unit analyzes the object to be measured using size and phase information of the signal received by the plurality of millimeter-wave transmission/reception units.

    摘要: A transit structure of a standard waveguide and a dielectric waveguide is related to connecting the dielectric dielectric waveguide to the standard waveguide. The transit structure includes: a cavity to match the dielectric waveguide and the standard waveguide, wherein the dielectric waveguide and the standard waveguide are orthogonal to each other to connect. The transit structure drastically reduces a design time by simply implementing a transit structure by using only a dielectric waveguide, a cavity and a standard waveguide on a dielectric substrate and remarkably reduces a size thereof in comparison with a conventional transit structure since all designs are finished in the size of a metal waveguide.
