    摘要: An end-fed planar type spiral antenna for transmitting/receiving radio signals includes a spiral pattern formed to have inner and outer spiral curves turned predetermined times in a spiral shape from an arbitrary center point in a plane; a central circle pattern formed in a part of a central region of the spiral pattern in a circular shape; and a feed arm pattern formed in a rectangular shape from an end of the spiral pattern that turns predetermined times. Conductive material is patterned on a pattern where the spiral pattern, the central circle pattern and the feed arm pattern are overlapped. This antenna allows to design an antenna structure capable of effectively enhancing radiation efficiency and improving broadband characteristics by utilizing a tapered spiral structure. Also, this antenna has an improved orientation, ensures less limitation in height, and allows a small-size design.

    摘要: The present invention relates to an apparatus and method for providing a bandwidth of a cognitive radio system. An apparatus and method for providing a bandwidth of a cognitive radio system according to an exemplary embodiment of the present invention calculates an oscillation frequency of a local signal that changes, by a predetermined value, center frequencies of fractional bands as bands that arc not used temporally and spatially in partial bands of an externally provided broadcasting channel band. The apparatus and method for providing a bandwidth of a cognitive radio system outputs a first local signal at the calculated oscillation frequency, mixes the output first local signal and an external signal, and moves center frequencies of fractional bands of the external signal by a predetermined value. The apparatus and method for providing a bandwidth of a cognitive radio system Filters a frequency band that is higher than an upper limit of a pass band having a predetermined bandwidth among moved frequency bands of the fractional bands to extract a first signal. Then, the apparatus and method for providing a bandwidth of a cognitive radio system mixes the extracted first signal and a second local signal and moves the center frequencies of the fractional bands in the first signal. The apparatus and method for providing a bandwidth of a cognitive radio system filters a frequency band that is lower than a lower limit of the pass band among the moved frequency bands of the fractional bands to extract at least one fractional band. The apparatus and method for providing a bandwidth of a cognitive radio system provides the extracted fractional band to a terminal and a base station, thereby improving frequency utilization efficiency.

    摘要: Erasure methods for a nonvolatile memory cell that includes a gate electrode on a substrate, source and drain regions in the substrate at respective sides of the gate electrode, and a charge storage layer interposed between the gate electrode and the substrate. A nonzero first voltage is applied to the source region starting at a first time. While continuing to apply the first nonzero voltage to the source region, a second voltage having an opposite polarity to the first voltage is applied to the gate electrode starting at a second time later than the first time. The second voltage may increase in magnitude, e.g., stepwise, linearly and/or along a curve, after the second time.
