摘要： An ultra wideband antenna is provided that filters a predetermined frequency signal. The ultra wideband antenna includes a power feeding part that receives a supply of an external electromagnetic energy; a radiator excited by the electromagnetic energy fed through the power feeding part and radiating an electromagnetic wave; and a stub, provided on the radiator in a direction parallel to a direction of an electric field formed by the electromagnetic wave, that intercepts transmission/reception of a predetermined frequency band signal. The length of the stub may be ¼ of a wavelength of the intermediate frequency of the predetermined frequency band to be removed to filter the corresponding frequency band signal. The ultra wideband antenna simplifies the construction of an ultra wideband receiving system with the power loss and noise characteristics of the system improved.

The terminal includes: a passive filter outputting a correlation signal between a received signal and a reference signal; and a wake-up controller controlling whether to wake up a communication module, using the correlation signal output from the passive filter. Thus, a wake-up signal can be processed using the passive element that does not consume power during its operation. Also, a wake-up of a communication module can be controlled using the result of processing the wake-up signal. As a result, power consumption can be greatly reduced during the wake-up.

摘要： Methods of forming integrated circuit devices utilize fine width patterning techniques to define conductive or insulating patterns having relatively narrow and relative wide lateral dimensions. A target material layer is formed on a substrate and first and second mask layers of different material are formed in sequence on the target material layer. The second mask layer is selectively etched to define a first pattern therein. Sidewall spacers are formed on opposing sidewalls of the first pattern. The first pattern and sidewall spacers are used collectively as an etching mask during a step to selectively etch the first mask layer to define a second pattern therein. The first pattern is removed to define an opening between the sidewall spacers. The first mask layer is selectively re-etched to convert the second pattern into at least a third pattern, using the sidewall spacers as an etching mask. The target material layer is selectively etched using the third pattern as an etching mask.
