  • Patent number: 7425923
    Abstract: Disclosed is a combined DMB and mobile communication antenna apparatus for a mobile communication terminal. The antenna apparatus includes one whip antenna for receiving both signals in a DMB frequency band and in a mobile communication frequency band, a first contact coupled to the whip antenna to receive the signal in the mobile communication frequency band from the whip antenna, and a second contact located under the first contact within a terminal main body and coming in contact with the whip antenna at a lower end of the whip antenna to receive the signal in the DMB frequency band when the whip antenna is drawn out.
    Type: Grant

  • Publication number: 20050140472
    Abstract: The present invention relates to a microstrip band pass filter and, more specifically, to a microstrip band pass filter using end-coupled stepped impedance resonators that can be used in a millimeter wave band, wherein the microstrip band pass filter comprises: a dielectric substrate; a conductor plate located on a lower surface of the dielectric substrate; and an input terminal, a plurality of SIRs and an output terminal located on an upper surface of the dielectric substrate in series, wherein the input terminal, the plurality of SIRs and the outputs terminal are conductors and end-coupled through gaps, whereby the microstrip band pass filter has a good attenuation characteristic and a narrowband characteristic, and is insensitive to the manufacturing error, and a fine frequency transition can be made without distortion just with width adjustment of the low impedance transmission line of the SIR.
