Abstract: A method of manufacturing a functional sheet according to an embodiment of the present invention, comprise powdering a filler with specific functional component and a binder, charging the filler and the binder with second polarity, spraying the binder and the filler onto an upper surface of an electrode plate charged with first polarity opposite to the second polarity, heat-treating the binder and filler, pressing an upper surface of the filler with a rolling roller, and separating the binder and the filler from the electrode plate. Therefore, the method can improve functionality while reducing harmfulness by manufacturing the functional sheet using a powdered filler and binder without using an organic solvent.

Abstract: Various embodiments of an antenna device for a wireless terminal are disclosed. The antenna device includes a radiator configured to be extracted from/retracted into the wireless terminal, a L-C lumped circuit, and a noise removing coil coupled between the radiator and the L-C lumped circuit, to attenuate noise introduced through the radiator. The radiator may be configured as a helical coil or at least one meandering printed pattern so as to reduce its overall length while maintaining a desired electrical length. In embodiments, the antenna device is useful for UHF/VHF frequency bands. Multi-band configurations are disclosed. In one embodiment, a stainless steel tube member substantially surrounds a helical coil, and the tube member operates at a lower frequency band than the helical coil.
