Ultra wide band antenna for filtering predetermined frequency band signal, and, ultra wide band signal receiving system therewith

摘要

The broadband antenna is disclosed for filtering a second predetermined frequency signal. The UWB antenna, feeding receiving the external electromagnetic energy by an electromagnetic energy feed through the feed here (excitation, 勵 起) is on the radiating element (radiator), and, radiating elements for emitting a predetermined electromagnetic wave, the electromagnetic wave is produced in a direction parallel to the direction of the electric field formed by a, a stub to block the transmission and reception of the predetermined frequency band signal. In this case, the stub is made of a quarter wave length of the center frequency signals of a predetermined frequency band to be removed. Accordingly, the frequency band signal is filtering. As a result, the second by a simplified configuration of a wideband signal receiving system, at the same time reducing the size it is possible to improve the power loss and the noise characteristics. ; UWB antenna, radiator, λ / 4 stub
