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： Provided are a wide band-differential chaos shift keying modulation method, a transmitting apparatus adopting the wide band-differential chaos shift keying modulation method, a wide band-differential chaos shift keying demodulation method, and a receiving apparatus adopting the wide band-differential chaos shift keying demodulation method. The wide band-differential chaos shift keying modulation method includes: generating a wide band chaotic signal; delaying the wide band chaotic signal; multiplying the delayed wide band chaotic signal by an information signal to output a multiplied signal; and performing a switching operation so as to alternately transmit the wide band chaotic signal and the multiplied signal. Thus, the invention can be realized without an APLL, a mixer, an FM modulator, and the like, to reduce power consumption and manufacturing cost for the transmitting apparatus. Thus, noise characteristics and security performance can be high, and the wide band-DCSK modulation method can be robust to multi-path.
