MULTIBAND AND MULTIPLEXER COMPRISING META-MATERIAL PHASE SHIFTER

摘要

PURPOSE: A multiplexer and multiband including a meta material phase shifter are provided to manufacture the multiband of the small size as one or more inductor and to short the box of a second multiplexer. CONSTITUTION: A receiving band filter(210) includes one or more first inductor for attenuation. The first inductor has a lumped element, the form of a distributed line, and the form of a meander line. The receiving band filter includes one or more resonator. A transmission band filter(230) includes one or more second inductor. The transmission band filter includes one or more resonator. A meta material phase shifter(220) is located between the receiving band filter and the transmitting band filter.
