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.

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.
