摘要： A multilayered coplanar waveguide (CPW) filter unit and a method of manufacturing the same are provided. A plate having a capacitance element is formed on or below a CPW layer including a signal line for transmitting a signal and a ground plane. As the filter unit has a multilayered structure, characteristic impedance may be reduced without increasing the width of the signal line. Where an inductor line is inserted between the signal line and the plate, a clear frequency response curve may be obtained without performing an additional process or increasing the area of the filter unit.

摘要： A parallel coupled line filter is miniaturized by using lumped capacitors and grounding the capacitors. The parallel coupled line filter includes a parallel coupled line, a first capacitor connected to one of two input ports of the parallel coupled line, and a second capacitor connected to one of two output ports of the parallel coupled line. The parallel coupled filter can be miniaturized to a desirable size, on the basis of relatively simple theoretical knowledge. The parallel coupled line filter exhibits excellent frequency selectivity and improved harmonic characteristics.

摘要： A wireless communication terminal and a method for controlling power and using a channel by adjusting a channel bandwidth of the wireless communication terminal. The wireless communication terminal generates a plurality of channels by dividing at least part of a frequency band for ultra-wideband communications to a plurality of frequency bands, receives a chaotic signal having a plurality of frequency components in the channels, and adjusts a frequency bandwidth which forms the channel when a certain condition is satisfied. Accordingly, since the chaotic carrier is transmitted and received in the narrow frequency band by adjusting the frequency bandwidth, the power consumption can be reduced drastically and the high-quality communications are feasible between the portable terminal and the wireless headset in the optimized channel environment. Furthermore, a greater number of portable terminals and wireless headsets can execute the radio communications in a certain wireless communication range.
