| 摘要 |
The present invention relates to a new type DC block using a DGS and a capacitor load which includes a pair of coupled lines which are arranged in parallel to one side of a dielectric element and blocks the flow of DC, a capacitor which is used as a load on both ends of the coupled line, and the DGS which is formed on a ground surface attached to the dielectric element by etching a partial region thereof. Thereby, the DC block is miniaturized. Impedance matching is performed even though impedance is different on both sides thereof. A wide stop-band and a wide pass-band are obtained. As a result, the present invention is used in a multiple band communication system and the size of a communication system is reduced. |
