    Abstract: PURPOSE: A communication apparatus for supporting multiband communication is provided to supply a duplex module which is able to support the multiband by using a single phase shifter. CONSTITUTION: A transmission signal filtering unit(210) filters an n numbers of multiband transmission signals. A first path setting unit(220) transfers one of the multiband transmission signals to an antenna unit(260). A phase shifter(230) splits the multiband transmission signal and the multiband reception signals by shifting the phase of the transferred multiband transmission signal. A second pant setting unit(240) connects the phase shifter to an n number of reception signal filters(250).

    Abstract: PURPOSE: The variable resonator including the meta material spirit and filter including the same interlinks the variable resonator including the meta material spirit as 2 shift. The resonant frequency variable range of the tunable device is exaggerated a lot. CONSTITUTION: The meta material(120) is connected to the transmission line(110). The meta material has the reversed phase of the transmission line and group velocity property of opposite. In the meta material under the above described conditions, the effective dielectric ratio and the fixed effective permeability altogether has the negative value.

    Abstract: A resonator, an apparatus having the same, and a method for manufacturing the resonator are provided to improve a roll off characteristic of an electronic component by freely adjusting an effective piezoelectric thin film coefficient in a wide range. A resonator includes a substrate(110), a resonating unit(135), and first and second electrode layers(141,142). The resonating unit includes a lower electrode, a piezoelectric film, and an upper electrode which are sequentially laminated on the substrate. The first and second electrode layers are made of the same material with differential crystalline properties, so that a resonance piezoelectric thin film coefficient is adjusted. One of grain sizes or surface roughness properties is different in the first and second electrode layers.
